Prerequisites

Installation Strategy

Choose one of the following installation strategies:

Download, then customize. Download the firmware image and configuration files to your TFTP server. Connect each phone to power, causing it to automatically download the image and default files. Configure each phone individually as needed.

Customize, then download. Download the firmware image and configuration files to your TFTP server. Open the configuration files and customize parameters for all the phones at once. Save the customized file to the TFTP server. Connect each phone to power, causing it to automatically download the image and customized files.

Network Functionality

Ensure that your network meets the following requirements:

A working IP network is established and configured for SIP.

For information on configuring IP, refer to the Cisco IOS IP Configuration Guide.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/ip_vcg.htm

VoIP is configured on your Cisco routers.

For information on configuring VoIP, refer to the Cisco IOS Voice Configuration Library.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/vcl.htm

VoIP gateways are configured for SIP.

A TFTP server is configured on your network.

When the phone initializes, it requests the following from the TFTP server:

Latest firmware image

Dual-boot file (OS79XX.TXT)

Phone-specific MAC-address configuration file

Default configuration file

Ring-list file

Dial-plan file

For information about configuring your TFTP server, refer to your operating-system documentation.

A DHCP server is configured on your network.

The phone can use DHCP to obtain IP addresses. Configuration options are as follows:

dhcp option #1 (IP subnet mask)

dhcp option #3 (default IP gateway)

dhcp option #6 (DNS server IP address)

dhcp option #15 (domain name)

dhcp option #50 (IP address)

dhcp option #66 (TFTP server IP address)

If you do not configure DHCP options on the DHCP server, you must manually configure them on the phone. For information on configuring a DHCP server, refer to your operating-system documentation.

A proxy server is active and configured to receive and forward SIP messages.


Note Refer to the Cisco 7940 and 7960 IP Phones Firmware Upgrade Matrix for additional prerequisites.


Overview of the Initialization Process

For an overview of the initialization process, refer to Cisco IP Phone 7960 and 7940 Firmware Upgrade Matrix, which is available at this URL:

http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/english/ipp7960/addprot/mgcp/
frmwrup.htm

Information About Configuration Files

Configuration files reside in a TFTP server subdirectory (you specify the location of this subdirectory with the tftp_cfg_dir parameter). For more information, refer to the Cisco 7940 and 7960 IP Phones Firmware Upgrade Matrix.


Note Be sure to customize configuration files before you power up the phone. When powered up, the phone automatically loads parameters stored in flash memory and then requests configuration files from the TFTP server.


When modifying parameters, remember the following:

Parameters in the configuration file override those stored in the phone's flash memory.

Locally changed parameters are used until the next reboot.

The name of each phone-specific configuration file is unique and is based on the MAC address of the phone.

The format of the filename must be SIPXXXXYYYYZZZZ.cnf, where XXXXYYYYZZZZ is the MAC address of the phone. The MAC address must be in uppercase; the .cnf extension must be in lowercase (for example, SIP00503EFFD842.cnf).


Note You can find the MAC address of a phone on the middle sticker adhered to the base of the phone. You can also view it on the Network Configuration menu.


Each line in a configuration file must use the following format and must adhere to the following rules:

variable-name : value ; optional comments

Associate only one value with one variable.

Separate variable names and values with colons.

Set only one variable per line.

Indicate the end of a line with <lf> or <cr><lf>.

Put the variable and value on the same line, and do not break the line.

You can include white space before or after a variable or value. You can include any character within them. However, if white spaces are needed within the value, you must enclose the value in single or double quotes. If the value is enclosed in quotes, the end quote must be the same as the start quote.

You can include comments after the value. Use the semicolon (;) and pound (#) delimiters to distinguish the comments.

You can include comment lines.

You can include blank lines.

You can use any case for variables; they are not case sensitive.

How to Customize the Default Configuration File

You have the following initialization choices:

Download, then customize. Download the default configuration file to your TFTP server, and then plug each phone into power and the network. The phones automatically download the default configuration file from the TFTP server. You can then customize parameters if required.

Customize, then download. Download the default configuration file to your TFTP server, open the file, customize parameters for all the phones at once, save the customized file, and then plug the phones into power and the network. The phones automatically download the customized file from the TFTP server.

This section describes how to customize, then download. Maintaining parameters—such as whether phones must register with a proxy server and the codec that phones must use when initiating a call—in the default configuration file allows you to perform global changes, such as upgrading the image version, without having to customize the phone-specific configuration file for each phone.


Note For a complete alphabetical list of configurable parameters, see "Configurable Parameters for the SIP IP Phone."


Prerequisites

If you have an existing system from a release earlier than Release 7.x, upgrade your system firmware as described in the "How to Upgrade Your Cisco SIP IP Phone Firmware Image" section before proceeding.

Procedure


Step 1 Obtain the default configuration file as follows:

a. Go to the Cisco.com SIP IP 7940/7960 phone software-download site at http://www.cisco.com/cgi-bin/tablebuild.pl/sip-ip-phone7960.

b. Download the SIPDefault.cnf file to the root directory of your TFTP server or to a subdirectory in which all phone-specific configuration files are stored.

Step 2 Using an ASCII text editor such as vi, open the file.

Step 3 Modify the following required parameters:

line1_name—Number or e-mail address for use when registering. Enter a number without dashes. For example, enter 555-0100 as 5550100. Enter an e-mail ID without the host name.

proxy1_address—IP address of the SIP proxy server that is used by the phones. Enter the address in IP dotted-decimal notation or use the FQDN.

proxy1_port—Port number of the SIP proxy server that is used by line 1.

Step 4 Modify additional parameters as needed.

How to Customize a Phone-Specific Configuration File

You can define parameters that are specific to a particular phone, such as the lines configured on a phone and the defined users for those lines, in a phone-specific configuration file.


NoteIf you configure a line to use an e-mail address, that line can be called only by using the e-mail address. Similarly, if you configure a line to use a number, that line can be called only by using the number. Each line can have a different proxy configured.

Define the dial_template parameter in the default configuration file for maintenance and control purposes. Define the parameter in a phone-specific configuration file only if that phone needs to use a different dial plan than the one being used by the other phones in the same system.

For a complete alphabetical list of configurable parameters, see "Configurable Parameters for the SIP IP Phone."


Procedure


Step 1 Obtain the phone-specific configuration file as follows:

a. Go to the Cisco.com SIP IP 7940/7960 phone software-download site at http://www.cisco.com/cgi-bin/tablebuild.pl/sip-ip-phone7960.

b. Download the SIP<mac-addr>.cnf file to the root directory of your TFTP server or to a subdirectory in which all phone-specific configuration files are stored.

Step 2 Do the following for each phone that you plan to install:

a. Using an ASCII text editor such as vi, create and open a SIP<mac-addr>.cnf file for the phone.

b. Modify the following end-user call-preference parameters as needed to permit or deny end-user use or customization:

anonymous_call_block

autocomplete

callerid_blocking

call_hold_ringback

call_waiting

dnd_control

c. Modify additional parameters as needed.

d. Save the file to the root directory of your TFTP server or to a subdirectory that contains all the phone-specific configuration files.

Name the file SIP<mac-addr>.cnf. Type the MAC address in uppercase and the extension, cnf, in lowercase (for example, SIP00503EFFD842.cnf).

How to Customize the Configuration from the Phone Menu

After the phone has been connected to power and initialized and the configuration files have been downloaded, you can modify your configuration using the phone menu.

This section contains the following procedures:

Unlocking and Locking the Phone

Setting and Restoring Network Parameters

Setting and Restoring Phone-Specific Parameters

Setting End-User Call Preferences


TipTo select a parameter, press the down arrow to scroll to and highlight the parameter, or press the number that represents the parameter (located to the left of the parameter on the LCD).

During configuration, use * for dots (periods) or press the "." soft key when available on the LCD.

During configuration:

To enter a number, press the Number soft key. To enter a name, press the Alpha soft key.

To enter a new value, use the buttons on the dial pad.

If entering letters, use the numbers on the dial pad that are associated with a particular letter. For example, the 2 key has the letters A, B, and C. For a lowercase a, press the 2 key once. To scroll through the available letters and numbers, press the key repeatedly.

To delete any mistakes, press the << soft key.

To cancel all changes and exit a menu during configuration, press Cancel.

After editing a parameter, press the Validate soft key to save the value that you have entered and exit the Edit panel.


Modifying your configuration using the phone menus requires that you unlock and relock the phone. A padlock icon in the upper-right corner of your LCD displays on the phone when the phone is locked. By default, the phone is locked.


Note If the Network Configuration or SIP Configuration menu is displayed, the lock icon in the upper-right corner of your LCD changes to an unlocked state. If you are located elsewhere in the Cisco IP Phone 7960G/7940G menus, the next time you access the Network Configuration or SIP Configuration menu, the unlocked icon displays, and you can modify the network and SIP configuration settings.


Unlocking and Locking the Phone

You must unlock and relock the phone to modify a configuration using the phone menus. Similarly, phone users must unlock and relock the phone to modify end-user parameters.

A padlock icon in the upper-right corner of your LCD displays on the phone when the phone is locked. By default, the phone is locked.

Prerequisites

Set the phone password with the phone_password parameter in the phone-specific configuration file.

Procedure


Step 1 To unlock the phone, do the following:

a. Press Settings > Unlock Config. The password prompt displays.

b. Enter a phone password. The phone unlocks, and the unlock icon displays on the LCD.


Note The Unlock Config menu choice changes to Lock Config and the configuration remains unlocked while you work within it. When you exit the configuration menu, the configuration automatically relocks.


Step 2 To relock the phone, select Lock Config or Exit.


Setting and Restoring Network Parameters

You can modify network parameters using the phone menus.


NoteTFTPServer may be a required parameter, depending on how you intend for the phone to locate the TFTP server from which it downloads its configuration file. You can provide the TFTP server IP address in either of two ways:

Provide it to the DHCP server. (For information, see the "Prerequisites" section.) Using normal Cisco Discovery Protocol (CDP) processes, the phone locates the DHCP server upon connection to the network; the server in turn provides the TFTP server address.

Provide it directly to the phone by means of the TFTPServer parameter as described in this procedure. If you use this method, first select DHCP Enabled > No.

Network parameters that can be modified are listed in Table 3-1. Those that cannot be modified are listed in Table 3-2.

For a complete alphabetical list of configurable parameters, see "Configurable Parameters for the SIP IP Phone."


Procedure


Step 1 Unlock the phone (see the "Unlocking and Locking the Phone" section).

Step 2 Select Settings > Network Configuration. The Network Configuration menu displays.

Step 3 To set a parameter, select it and set it as desired.

Step 4 To restore all parameters to their defaults, select Erase Config > Yes.


Note If DHCP is disabled on a phone, restoring default phone settings reenables DHCP.


Step 5 Select Save. The phone programs the new information into flash memory and resets.

Step 6 Relock the phone.


Table 3-1 Network Parameters That Can Be Modified 

Parameter
Description

Admin. VLAN Id1

Unique identifier of the VLAN to which the phone is attached (for use in switched networks that are not Cisco networks).

Alternate TFTP

Whether to use an alternate remote TFTP server rather than the local one.

Valid values are Yes and No. If you set this parameter to Yes, you must change the IP address in the TFTP server parameter to the address of the alternate TFTP server. Default is No.

Default Router 1 to 52

IP address (1) of the default gateway used by the phone and (2 to 5) of the gateways that the phone attempts to use as an alternate gateway if the default gateway is unavailable.

DHCP Address Released

Whether the IP address of the phone can be released for reuse in the network.

Valid values are Yes and No. When set to Yes, the phone sends a DHCP release message to the DHCP server and goes into a release state. The release state provides enough time to remove the phone from the network before the phone attempts to acquire another IP address from the DHCP server. When you move the phone to a new network segment, first release the DHCP address.

DHCP Enabled

Whether the phone uses DHCP to configure network settings (IP address, subnet mask, domain name, default router list, DNS server list, and TFTP address).

Valid values are Yes and No. To manually configure your IP settings, you must set this parameter to No. Default is Yes.

DNS Servers 1 to 52

IP address of the DNS server used by the phone to resolve names to IP addresses. The phone attempts to use DNS servers 2 to 5 if DNS server 1 is unavailable.

Domain Name

Name of the DNS domain in which the phone resides.

Erase Configuration

Whether to erase all of the locally defined network settings on the phone and reset the values to the defaults.

Valid values are Yes and No. Yes reenables DHCP. For information on erasing the local configuration, see the "Setting and Restoring Network Parameters" section.

HTTP Proxy Address

IP address of the HTTP proxy server. You can use either a dotted IP address or a DNS name (a record only).

HTTP Proxy Port

Port number of the outbound proxy port. Default is 80.

IP Address2

IP address of the phone that is assigned by DHCP or that is locally configured.

Network Media Type

Ethernet port negotiation mode. Valid values are as follows:

Auto—Port is autonegotiated.

Full-100—Port is configured to be a full-duplex, 100-MB connection.

Half-100—Port is configured to be a half-duplex, 100-MB connection.

Full-10—Port is configured to be a full-duplex, 10-MB connection.

Half-10—Port is configured to be a half-duplex, 10-MB connection.

Default is Auto.

Network Port 2 Device Type

Device type that is connected to port 2 of the phone. Valid values are Hub/Switch and PC. Default is Hub/Switch.

Note If the value is PC, port 2 can be connected only to a PC. If you are not sure about the connection, use the default value. Using a value of PC and connecting port 2 to a switch could result in spanning-tree loops and network confusion.

Subnet Mask2

IP subnet mask used by the phone. A subnet mask partitions the IP address into a network and a host identifier.

TFTP Server2

IP address of the TFTP server.

1 If you have an administrative VLAN setting assigned on the Cisco Catalyst switch, that setting overrides any changes made on the phone.

2 DHCP must be disabled.


Table 3-2 Network Parameters That Cannot Be Modified 

Parameter
Description

DHCP Server

IP address of the DHCP server from which the phone received its IP address and additional network settings.

Dynamic DNS Server 1 and 2

IP address of a dynamic DNS server.

Dynamic TFTP Server

IP address of a dynamic TFTP server.

Host Name

Unique host name assigned to the phone.

MAC Address

Factory-assigned unique 48-bit hexadecimal MAC address of the phone.

Operational VLAN Id

Unique identifier of the VLAN of which the phone is a member.


Setting and Restoring Phone-Specific Parameters

Phone users can modify the phone-specific configuration settings using the phone menus.


NoteParameters defined in the phone-specific configuration file override those specified in the phone-specific configuration file.

If a phone-specific configuration file exists, the phone uses parameters entered locally until the next reboot.

If you do not configure the phone using a TFTP server, you must configure the phone locally.

To configure the preferred codec and out-of-band DTMF parameters, press Change until the option displays and then press Save.

If your system has been set up to have the phones retrieve the configuration file from a TFTP server, you must use the server's configuration file to change the parameter value to a null value " " or to "UNPROVISIONED." The phone uses the setting for that variable that it has stored in flash memory.

If the telnet_level parameter is set to allow privileged commands to be executed, the entire SIP configuration can be erased. Use the erase_protflash command so that the phone can retrieve its configuration files.


Prerequisites

Define the line parameters (those identified as linex) on the phone. If you configure a line to use an e-mail address, that line can be called only by using an e-mail address. Similarly, if you configure a line to use a number, that line can be called only by using the number.

Procedure


Step 1 Unlock the phone (see the "Unlocking and Locking the Phone" section).

Step 2 Select Settings > SIP Configuration. The SIP Configuration menu displays.

Step 3 To set a required parameter, select it and set it as desired. The following are required parameters that you must set now if you did not set them in the default configuration file as described in the "How to Customize the Default Configuration File" section:

line1_name—Number or e-mail address for use when registering. Enter a number without dashes. For example, enter 555-0100 as 5550100. Enter an e-mail ID without the host name.

proxy1_address—IP address of the SIP proxy server that is used by the phones. Enter the address in IP dotted-decimal notation or use the FQDN. The "x" argument is representative of server addresses. If the parameter is provisioned with an FQDN, the phone sends REGISTER and INVITE messages by using the FQDN in the Req-URI, To, and From fields.

proxy1_port—Port number of the SIP proxy server that is used by line 1.

If the proxy server with which the phone communicates has authentication enabled, set the following parameters as well:

line1_authname—Name used by the phone for authentication if a registration is challenged by the proxy server during initialization. Default is UNPROVISIONED.

line1_password—Password used by the phone for authentication if a registration is challenged by the proxy server during initialization. Default is UNPROVISIONED.

Step 4 To set an additional parameter, select it and set it as desired. Phone-specific parameters are listed in Table 3-3.

Step 5 To restore a parameter to its default, do the following:

a. One at a time, highlight the parameter whose setting you want to erase, and then select Edit followed by <<.

b. Select Validate > Exit.

c. If necessary, select Back to exit the menu.

Step 6 Select Save. The phone programs the new information into flash memory and resets.


Table 3-3 Phone-Specific Parameters 

Parameter
Description

Authentication Name1

Name used by the phone for authentication if a registration is challenged by the proxy server during initialization.

Authentication Password1

Password used by the phone for authentication if a registration is challenged by the proxy server during initialization. If a value is not configured for the Authentication Password parameter when registration is enabled, the default logical password is used. The default logical password is SIPmac-address, where mac-address is the MAC address of the phone.

Display Name

Identification as it should appear for caller identification. For example, instead of jdoe@company.com appearing on phones that have caller ID, you can specify John Doe in this parameter to have John Doe appear on the callee end instead. If a value is not specified for this parameter, the Name value is used.

Name

Description phone number or e-mail address used when registering. When entering a number, enter the number without any dashes. For example, enter 555-0100 as 5550100.

Proxy Address

IP address of the primary SIP proxy server that will be used by the phone. Enter this address in IP dotted-decimal notation.

Proxy Port

Port number of the primary SIP proxy server. This is the port that the SIP client will use. The default is 5060.

Short Name

Name or number associated with the linex_name as you want it to display on the phone LCD if the linex_name value exceeds the display area. For example, if the linex_name value is the phone number 111-222-333-4444, you can specify 34444 for this parameter to have 34444 display on the LCD instead. Alternatively, if the value for the linex_name parameter is the e-mail address "username@company.com," you can specify the "username" to have just the username appear on the LCD instead. This parameter is used for display only. If a value is not specified for this parameter, the value in the Name variable is displayed.

1 Required when registration is enabled and the registrar challenges registration.


Setting End-User Call Preferences

End users can modify call preferences from their own phones, according to how you set the associated parameters.

Prerequisites

Set configuration variables for call preferences as follows (see the "How to Customize a Phone-Specific Configuration File" section):

To enable end users to modify a preference, set to 0 or 1.

To prohibit end users from modifying a preference, set to 2 or 3.

Procedure


Step 1 On the IP phone, select Settings > Call Preferences.

Step 2 Set any of the following preferences to the desired setting:

Anonymous Call Block

Auto Answer (Intercom)

Auto-Complete Numbers

Caller ID Blocking

Call Hold Ringback

Call Waiting

Do Not Disturb

Stutter Msg waiting

Step 3 Select Save. The phone programs the new information into flash memory and resets.

Step 4 Relock the phone.


How to Set the Date and Time

You can set date, time, and daylight savings time (DST) parameters. The current date and time is supported on the Cisco IP Phone 7960G/7940G using Simple Network Time Protocol (SNTP) and is displayed on the LCD. DST and time-zone settings are also supported.

International time-zone abbreviations are supported and must be in all capital letters.


Note We recommend that you set date- and time-related parameters in the default file for all phones. Alternatively, you can set the time-zone parameter manually on the phone or in the phone-specific configuration files.


Prerequisites

Determine the type of DST that you want to configure:

Absolute DST (for example, starts on April 1 and ends on October 1)

Relative DST (for example, starts on the first Sunday in April and ends on the last Sunday of October)

Review the list of common and absolute DST parameters from "Configurable Parameters for the SIP IP Phone."

Review the information on SNTP in Table 3-4. SNTP parameters specify how the phone obtains the current time from an SNTP server.

Determine your time zone from Table 3-5.

Procedure


Step 1 Using an ASCII text editor such as vi, open the SIPDefault.cnf file.

Step 2 Modify the following SNTP parameters as needed:

sntp_mode

sntp_server

time_zone

Step 3 Modify the following common DST parameters as needed:

dst_offset

dst_auto_adjust

dst_start_month

dst_stop_month

dst_start_time

dst_stop_time

Step 4 Do one of the following:

Modify the following absolute DST parameters as needed:

dst_start_day

dst_stop_day

Modify the following relative DST parameters as needed:

dst_start_day_of_week

dst_start_week_of_month

dst_stop_day_of_week

dst_stop_week_of_month

Step 5 Save the file to the root tftp directory of your TFTP server.


Note To adjust the phone display to European Day-Month-Year format, add the following entry to the SIPDefault.cnf file: date_format:D/M/Y.



Table 3-4 describes the effects on SNTP mode when the SNTP server is null (not assigned an IP address) or when it is assigned a valid IP address.

How to Create Dial Plans

Dial plans enable the Cisco SIP IP phone to support automatic dialing and generation of a secondary dial tone. If a single dial plan is used for a system of phones, the dial plan is best specified in the default configuration file.

However, you can also create multiple dial plans and specify which phones are to use which dial plan by defining the dial_template parameter in the phone-specific configuration file. If one phone in a system of phones needs to use a different dial plan than the rest, you need to define a dial plan for that phone in its phone-specific configuration file.

Prerequisites

Ensure that your dial plans adhere to the following:

They are written with the understanding that rules are matched from start to finish with the longest matching rule taken as the one to use. Matches against a period are not counted as part of the longest length.

They are in XML format.

They are stored on your TFTP server.

Specify which dial plan a phone is to use by specifying the path to the dial plan in the dial_template parameter. Define the dial_template parameter in either the default configuration file or a phone-specific configuration file.


Note To simplify maintenance and control, define this parameter in the default configuration file. Define it in a phone-specific configuration file only if that phone needs to use a different dial plan than the one being used by the other phones in the same system.


Procedure


Step 1 Using an ASCII text editor such as vi, open a new file.

Step 2 Type the following to indicate the start of the dial-plan template:

<DIALTEMPLATE>

Step 3 For each of the numbering schemes that you require, add the following string to the template, each starting on a separate line:

TEMPLATE MATCH="pattern" Timeout="sec" User="type" Rewrite="xxx" Route="route" Tone="tone"

Arguments are as follows:

Argument
Description
TEMPLATE MATCH="pattern"

Dial-pattern string to match. You can use the following wildcards:

A period (.) matches any character.

An asterisk (*) matches one or more characters.

A comma (,) causes the phone to generate a secondary dial tone.

Timeout="sec"

Time, in seconds, before the system times out and dials the number as entered by the user. To have the number dial immediately, specify 0.

User="type"

Tag to be added automatically to the dialed number. Valid values are IP and Phone. This tag is not case sensitive.

Rewrite="xxx"

Alternate string to be dialed instead of the number that the user dials. The following apply:

Rewrite rules are matched from start to finish with the longest matching rule taken as the one to use.

Matches against a period are not counted as part of the length.

A complete rule is matched only if it has more nonwildcard matches than an incomplete rule.

Comments are allowed with the following syntax:

<!-- comment -->

Rules allow for substitution of up to five replacement strings as well as picking off of replaced digits one at a time.

For example, a match string of ab..cd..ef* and an input string of ab12cd34ef5678 result in the following.

Rewrite
Output
Notes
 
%s
ab12cd34ef5678

 
%0
ab12cd34ef5678

 
%1
12


%2
34

 
%3
5678

 
%4

Null output.

 
%5

Null output.

 
XYZ....
XYZ1234

 
X.Y.Z...
X1Y2Z345

 
919%1%2%3
91912345678

 
AB...X%1X..
AB123X12X45

12 appears twice.

 
X%1X%1X%1
X12X12X12

You can reuse the string.

 
X%s%%
Xab12cd34ef5678

%% produces a %.

 
919
919

No need to use the input.

 
............
12345678

Nothing goes in for the extra dots.

Route="route"

Proxy to which to route the call. Valid values are default, emergency, and FQDN. FQDN is treated the same as default proxy. This entry is not case sensitive.

Tone="tone"

User-specific dial tone. If no tone is specified, the default secondary dial tone plays. If a comma (,) is specified followed by a tone, the phone plays the indicated tone instead of the secondary dial tone. If a tone is specified but there is no comma, the tone is ignored.

You can specify up to three different secondary dial tones in a single dial-plan template. The tones play in the order in which they appear in the template. Multiple tone entries are condensed into a single comma. For example, the phone interprets the match string 9,,,234 as 9,234 and treats the three commas as a single comma.


Step 4 Specify the pound sign (#) and asterisk (*) as dialed digits if required.

The # is processed as a "dial now" event by default. You can override this by specifying # in the dial-plan template, in which case the phone does not dial immediately when the # is pressed but does continue to match the dial-plan template that specifies the #. The # is not matched by the wildcard character * or the period (.).

The * is processed as a wildcard character. You can override this by preceding the * with the backward slash (\) escape sequence, resulting in the sequence \*. The phone automatically strips the \ so that it does not appear in the outgoing dial string. When * is received as a dialed digit, it is matched by the wildcard characters * and period (.).

Step 5 Specify the comma (,) as a secondary dial tone if required.

In earlier releases, a comma in the dial-plan template caused the phone to play the default secondary dial tone (Bellcore-Outside). With this release, you can specify which tones are played. All tone names should begin with a common prefix. Tone names, which are case insensitive, are as follows:

Bellcore-Alerting

Bellcore-dr5

Bellcore-Reorder

Bellcore-Busy

Bellcore-dr6

Bellcore-Stutter

Bellcore-BusyVerify

Bellcore-Hold

CallWaiting-2

Bellcore-CallWaiting

Bellcore-Inside

CallWaiting-3

Bellcore-Confirmation

Bellcore-None

CallWaiting-4

Bellcore-dr1

Bellcore-Outside (default)

Cisco-BeepBonk

Bellcore-dr2

Bellcore-Permanent

Cisco-Zip

Bellcore-dr3

Bellcore-Reminder

Cisco-ZipZip

Bellcore-dr4

   

If desired, specify <!--comment--> at the end of each string to denote the type of plan (for example,

<!-- Long Distance --> or <!-- Corporate Dial Plan -->).


Note For more information on Bellcore tones, refer to Bellcore GR-506-CORE. For more information on tones in BTS 10200 Softswitch features, refer to the Cisco BTS 10200 Softswitch website at http://www.cisco.com/en/US/partner/products/hw/vcallcon/ps531/index.html.


Step 6 Type the following to indicate the end of the dial-plan template:

</DIALTEMPLATE>

Step 7 Give the file a unique name specific to the dial plan that it defines and save it with a .xml extension to your TFTP server.

Step 8 If the dial plan applies to a specific phone, add the path to the dial plan (without specifying the file type of .xml) via the dial_template parameter in the phone-specific configuration file. If the dial plan applies to a system of phones, add the path to the dial plan via the dial_template parameter in the default configuration file.


Dial-Plan Configuration Examples

Using the Pound-Sign (#) Character

The following example uses the pound sign (#) as a dialed digit:

<DIALTEMPLATE>
	<TEMPLATE MATCH="123#45#6" TIMEOUT="0" User="Phone"/> <!-- Match `#' -->
	<TEMPLATE MATCH="34#..."    TIMEOUT="0" User="Phone"/> <!-- Match `#' -->
	<TEMPLATE MATCH="*"      TIMEOUT="15" User="Phone"/>
</DIALTEMPLATE>

In the example above, the 123#45#6 string is matched if the user dials 123#45#6. Pressing the pound sign (#) does not cause the phone to dial immediately because # is explicitly specified. However, dialing 1# or 123#4# causes the phone to dial immediately.

Using the Backward-Slash (\) and Asterisk (*) Characters

The following example uses the backward slash (\) and asterisk (*) as a dialed digit:

<DIALTEMPLATE>
	<TEMPLATE MATCH="12\*345" TIMEOUT="0" User="Phone"/> <!-- Match * Char -->
	<TEMPLATE MATCH="*"        TIMEOUT="10" User="Phone"/> <!-- Wildcard -->
</DIALTEMPLATE>

If you use the backslash (\) on a character other than the asterisk (*), the \ is ignored and the \\ character is matched. If you need to explicitly specify the \ character in a dial plan, use \\. The \ is not sent out as part of the dialed digit string because the phone removes it before sending the dial string.


Note The \* character is matched by the "." character.


Specifying a Secondary Dial Tone

The following example specifies two different tones:

<DIALTEMPLATE>
	<TEMPLATE MATCH="7,..." TIMEOUT="0" /> <!-- Default Secondary Dial Tone -->
	<TEMPLATE MATCH="9,..." TIMEOUT="0" Tone="Zip" /> <!-- Play Zip Tone -->
	<TEMPLATE MATCH="8,...." TIMEOUT="0" Tone="Hold" /> <!-- Play Hold Tone -->
	<TEMPLATE MATCH="8,123,...." TIMEOUT="0" Tone="Hold" Tone="Zip" /> <!--Play Hold Tone 
                                 after 8, Play Zip Tone after 123-->
</DIALTEMPLATE>

How to Verify Initialization

The initialization process establishes network connectivity and makes the phone operational in your IP network.

Procedure


Step 1 After the phone has power connected to it, ensure that the phone cycles through the following steps:

a. The following flash on and off in sequence: Headset button, Mute button, and Speaker button.

b. The Cisco Systems, Inc. copyright appears on the LCD.

c. The following messages appear:

Configuring VLAN—The phone configures the Ethernet connection.

Configuring IP—The phone contacts the DHCP server to obtain network parameters and the IP address of the TFTP server.

Requesting Configuration—The phone contacts the TFTP server to request its configuration files and compares firmware images.

Upgrading Software—The phone displays this message only if it determines that an image upgrade is required. After upgrading the image, the phone automatically reboots to run the new image.

d. The main LCD displays the following:

Primary directory number

Soft keys

If the phone successfully cycles through these steps, it has started up properly.
