Information About Setting Up Cisco Unified IP Phones

Cisco Unified IP Phone configuration is limited for Cisco Unified SRST because IP phones retain nearly all Cisco Unified Communications Manager settings during Cisco Unified Communications Manager fallback. You can configure the date format, time format, language, and system messages that appear on Cisco Unified IP Phones during Cisco Unified Communications Manager fallback. All four of these settings have defaults, and the available language options depend on the IP phones and Cisco Unified Communications Manager version in use. Also available for configuration is a secondary dial tone, which can be generated when a phone user dials a predefined PSTN access prefix and can be terminated when additional digits are dialed. Dual-line phone configuration is required for dual-line phone operation during Cisco Unified Communications Manager fallback.

How to Set Up Cisco Unified IP Phones

This section contains the following tasks:

•Configuring IP Phone Clock, Date, and Time Formats (Optional)

•Configuring IP Phone Language Display (Optional)

•Configuring Customized System Messages for Cisco Unified IP Phones (Optional)

•Configuring a Secondary Dial Tone (Optional)

•Configuring Dual-Line Phones (Required Under Certain Conditions)

•Configuring Eight Lines Per Button (Octo-Line) (Optional)

Configuring IP Phone Clock, Date, and Time Formats

The Cisco Unified IP Phone 7970G and Cisco Unified IP Phone 7971G-GE IP phones obtain the correct timezone from Cisco Unified Communications Manager. They also receive the Coordinated Universal Time (UTC) time from the SRST router during SRST registration. When in SRST mode, the phones take the timezone and the UTC time, and apply a timezone offset to produce the correct time display.

Cisco IP Phone 7960 IP phones and other similar SCCP phones such as the Cisco IP Phone 7940, get their display clock information from the local time of the SRST router during SRST registration. If the Cisco Unified SRST router is configured to use the Network Time Protocol (NTP) to automatically sync the Cisco Unified SRST router time from an NTP time server, only UTC time is delivered to the router. This is because the NTP server could be physically located anywhere in the world, in any timezone. As it is important to display the correct local time, use the clock timezone command to adjust or offset the Cisco Unified SRST router time.

The date and time formats that appear on the displays of all Cisco Unified IP Phones in Cisco Unified Communications Manager fallback mode are selected using the date-format and time-format commands as configured below:

SUMMARY STEPS

1. clock timezone zone hours-offset [minutes-offset]

Configuring Customized System Messages for Cisco Unified IP Phones

Use the system message command to customize the system message displayed on all Cisco Unified IP Phone 7910, Cisco Unified IP Phone 7940G, and Cisco Unified IP Phone 7960G units during Cisco Unified Communications Manager fallback.

One of two keywords, primary and secondary, must be included in the command. The primary keyword is for IP phones that can support static text messages during fallback, such as the Cisco IP Phone 7940 and Cisco IP Phone 7960 units. The default display message for primary IP phones in fallback mode is "CM Fallback Service Operating."

The secondary keyword is for Cisco Unified IP Phones that do not support static text messages and have a limited display space, such as the Cisco IP Phone 7910. Secondary IP phones flash messages during fallback. The default display message for secondary IP phones in fallback mode is "CM Fallback Service."

Changes to the display message will occur immediately after configuration or at the end of each call.

Note The normal in-service static text message is controlled by Cisco Unified Communications Manager.

Configuring Dual-Line Phones

Dual-line phone configuration is required for dual-line phone operation during Cisco Unified Communications Manager fallback. Consultative transfer is also required (see the "Enabling Consultative Call Transfer and Forward Using H.450.2 and H.450.3 with Cisco SRST 3.0" section on page 98).

Dual-line IP phones are supported during Cisco Unified Communications Manager fallback using the max-dn command. Dual-line IP phones have one voice port with two channels to handle two independent calls. This capability enables call waiting, call transfer, and conference functions on a phone-line button.

In dual-line mode, each IP phone and its associated line button can support one or two calls. Selection of one of two calls on the same line is made using the blue Navigation button located below the phone display. When one of the dual-line channels is used on a specific phone, other phones that share the ephone-dn will be unable to use the secondary channel. The secondary channel will be reserved for use with the primary dual-line channel.

It is recommended that hunting be disabled to the second channel. For more information, see the "Configuring Dial-Peer and Channel Hunting" section on page 94.

SUMMARY STEPS

1. call-manager-fallback

2. max-dn max-directory-numbers [dual-line] [preference preference-order]

3. exit

DETAILED STEPS

Command or Action

Purpose

Step 1

call-manager-fallback
Example:

Router(config)# call-manager-fallback

Enters call-manager-fallback configuration mode.

Step 2

max-dn max-directory-numbers [dual-line] [preference preference-order]
Example:

Router(config-cm-fallback)# max-dn 15 dual-line preference 1

Sets the maximum number of directory numbers (DNs) or virtual voice ports that can be supported by the router and activates dual-line mode.

•max-directory-numbers: Maximum number of directory numbers or virtual voice ports supported by the router. The maximum number is platform-dependent. The default is 0. See the "Platform and Memory Support" section on page 37 for further details.

•dual-line (Optional). Allows IP phones in Cisco Unified Communications Manager fallback mode to have a virtual voice port with two channels.

•preference preference-order (Optional). Sets the global preference for creating the VoIP dial peers for all directory numbers that are associated with the primary number. Range is from 0 to 10. Default is 0, which is the highest preference.

The alias command also has a preference keyword that sets alias command preference values. Setting the alias command preference keyword allows the default preference set with the max-dn command to be overridden. See Configuring Call Rerouting, page 79 for more information on using the max-dn command with the alias command.

Step 3

exit
Example:

Router(config-cm-fallback)# exit

Exits call-manager-fallback configuration mode.

Examples

The following example sets the maximum number of DNs or virtual voice ports that can be supported by a router to 10 and activates the dual-line mode for all IP phones in Cisco Unified Communications Manager fallback mode.
call-manager-fallback
 max-dn 10 dual-line
 exit
Configuring Eight Lines Per Button (Octo-Line)

The octo-line feature supports up to eight active calls, both incoming and outgoing, on a single button. Eight incoming calls to an octo-line directory number ring simultaneously. After an incoming call is answered, the ringing stops and the remaining seven incoming calls hear a call waiting tone.

After an incoming call on an octo-line directory number is answered, the answering phone is in the connected state. Other phones that share the directory number are in the remoteMultiline state. A subsequent incoming call sends the call waiting tone to the phone connected to the call, and sends the ringing tone to the other phones that are in the remoteMultiline state. All phones sharing the directory number can pick up any of the incoming unanswered calls.

When multiple incoming calls ring on an octo-line directory number that is shared among multiple phones, the ringing tone stops on the phone that answers the call, and the call waiting tone is heard for other unanswered calls. The multiple instances of the ringing calls is displayed on other ephones sharing the directory number. After a connected call on an octo-line directory number is put on-hold, any phone that shares this directory number can pick up the held call. If a phone is in the process of transferring a call or creating a conference, other phones that share the octo-line directory number cannot steal the call.

As new calls come in on an octo-line, the system searches for the next available idle line using the huntstop chan tag command, where tag is a number from 1 to 8. An idle channel is selected from the lowest number to the highest. When the highest number of allowed calls is received, the system stops hunting for available channels. Use this command to limit the number of incoming calls on an octo-line directory number and reserve channels for outgoing calls or features such as call transfer or conference calls.

With the new feature you can:

•Configure only dual-line mode

•Configure only octo-line mode

•Configure dual-line mode and octo-line mode

Prerequisites

•Cisco Unified SRST 7.0/4.3

•Cisco Unified Communications Manager 6.0
