What's New in this Release
The following sections describe new and enhanced features in this release:
•
•
•
•
Additional Time Zones Support
The TimeZone parameter has been enhanced to provide support for time zones that are offset by increments of 30 minutes and 45 minutes. This parameter continues to support the integers 0 through 24 for time zones that are offset by 60 minute increments, as shown in Table 1.
With this release, the TimeZone parameter can also accept the integers -720 through -60 and 60 through 780. These integers specify the time zone offset in minutes from GMT and are used for locations with time zone offsets of 30 minutes and 45 minutes increments.
The formula for calculating the TimeZone parameter value in minutes is:
(offset hours * 60 minutes/hour) + offset minutes = total minutes
For example, for the Darwin time zone of GMT + 9:30, the calculation is:
(9 hours * 60 minutes/hour) + 30 minutes = 570 minutes
Table 2 shows examples of TimeZone parameter values for time zones with offsets of 30 minutes and 45 minutes increments.
D Rule for Displaying Caller ID
The D rule has been added to the DialPlan parameter. This rule lets you specify a called number for which caller ID is always displayed, even if you have blocked caller ID.
The syntax for the D rule is:
Dnnnn
where nnnn is a called number to which caller ID is always displayed. The D rule is checked before the R rule.
The called number nnnn can be specified using negation, subrule matching, and range. For more information, see the "Advanced Syntax for Dial Plan Rules" section.
Example
The following dial plan rule causes caller ID to always be displayed when the called number is 911:
D911
Log Information
The following lines will be written to the prserv log file when the dialed number matches the the number specified for the D rule.
Note
SCC Cmd[0,call_id]:CLIPCLIP: numwhere:
•
•
R Rule for Enhanced Prefix
The R rule has been added to the DialPlan parameter. This rule is for automatically prepending a specified prefix to the dialed string. If more than one R rule matches, the first matched R rule is used.
The syntax for the R rule is:
R[-]nnnn(tttt)
where:
•
•
•
The trigger string tttt can be specified using negation, subrule matching, and range. For more information, see the "Advanced Syntax for Dial Plan Rules" section
Examples
Table 3 shows three examples of the R dial plan rule.
Log Information
The following line will be written to the prserv log file when the dialed string matches the R rule:

Advanced Syntax for Dial Plan Rules
You can use the commands shown in Table 4 to specify the called number (nnnn) in the D dial plan rule and the trigger string (tttt) in the R dial plan rule.
Note
Examples
Table 5 shows examples of the dial plan rules advanced syntax.
G.729 Annex B Support
The Cisco IP Phone models 7905G and 7912G for SIP indicate G.729 Annex B codec support by using a=fmtp and a=rtpmap attribute in the SDP body of outgoing INVITE requests and 183 and 200 responses to INVITE requests. For the G.729 codec, the value of a=ftmp is 18 and the annexb value is either yes or no. The default for annexb is yes.
Table 6 lists the possible G.729 codec configuration and resulting negotiated codec.
The following partial SDP body shows the media m= field and attribute a= field for a phone with G.729 codec and Annex B specified:
m=audio 16384 RTP/AVP 18 101a=rtpmap:18 G729/8000/1a=fmtp:18 annexb=yesSelectable Host Target for Forwarded Calls
You can now set bit 0 in the ConnectMode parameter to designate the destination of the new INVITE request that results from a forwarded call.
You can set bit 0 to 0 or 1, where:

EncryptKeyEx Parameter
EncryptKeyEx is a new configuration parameter for the Cisco IP Phones models 7905G and 7912G (SIP). This parameter provides a stronger configuration file encryption key than the previously used EncryptKey parameter.
Syntax
The syntax of the EncryptKeyEx parameter is:
EncryptKeyEx:rc4KeyInHex_n[/macInHex_12]
where:
•
•
Description
When the EncryptKeyEx parameter is set to 0, the Cisco IP Phone TFTP configuration file name is ldMAC_address (for the Cisco IP Phone 7905G) or gkMAC_address (for the Cisco IP Phone 7912G). MAC_address is the lowercase hexadecimal representation of the phone's MAC address. For example, if the Cisco IP Phone 7905G has a MAC address of 102030405060, the TFTP configuration file name is ld102030405060
Note
When the value of EncryptKeyEx is 0, the value of EncryptKey (if nonzero) is used to encrypt the Cisco IP phone configuration file.
If the EncryptKeyEx parameter is set to value other than 0, the configuration file name is ldMAC_address.x (for the Cisco IP Phone 7905G) or gkMAC_address.x (for the Cisco IP Phone 7912G), and the value of the EncryptKeyEx parameter is used to encrypt the Cisco IP phone profile file.
Note
Tool Required
You must use release 2.3 of the cfgfmt tool with the new EncryptKeyEx parameter. This tool is bundled with the Cisco IP Phone models 7905G and 7912G software release 1.2.0 and later. This tool creates two configuration files, one file named ldMAC_address format (for the Cisco IP Phone 7905G) or gkMAC_address (for the Cisco IP Phone 7912G), as the previous release of the cfgfmt tool created, and one with the .x extension.
See the "New cfgfmt Tool" section for information about using the cfgfmt tool with the EncryptKeyEx parameter.
Examples
The following examples use the TFTP configuration method to illustrate how to use the EncryptKeyEx parameter.
Example 1
This example assumes that a Cisco IP Phone 7912G starts with a firmware release earlier than 1.2.0 and that phone needs to upgrade to firmware release 1.2.0 so that it can use the EncryptKeyEx parameter to encrypt its configuration file.
The Cisco 7912G IP phone in this example has a MAC address of 102030405060.
Procedure
Step 1
(The example.txt file is called sipexample.txt.)
Step 2
The value of the EncryptKey parameter should be 0.
Step 3
You can also restrict the EncryptKeyEx value to apply only to the Cisco IP Phone 7912G with a particular MAC address. For example, if the EncryptKeyE value is 231e2a7f10bd7fe, you can specify EncryptKeyEx as:
EncryptKeyEx:231e2a7f10bd7fe/102030405060
With this setting, only the phone with the MAC address 102030405060 will be allowed to use the EncryptKeyEx value specified.
Step 4
In this example, you would modify this parameter as follows for the Cisco 7912G IP phone:
upgradecode:3,0x601,0x0400,0x0100,0,69,0x030909a,CP7912010200SIP040101.zup
Step 5
cfgfmt -g -tsip_ptag.dat gk102030405060.txt gk102030405060
This command will generate the following files:
gk102030405060
gk102030405060.x
The file gk102030405060 is unencrypted.
Note
The file gk102030405060.x is encrypted with EncryptKeyEx value.
Step 6
When the phone powers up, it will obtain its IP address from the DHCP server. If the DHCP server specifies the TFTP server address, the phone will contact the TFTP server obtained from DHCP because the phone is not preconfigured with a TFTP server address. The boot process is as follows:
1.
2.
3.
4.
5.
6.
7.
8.
Note
Example 2
This example assumes that a Cisco IP Phone 7912G is already deployed (with the EncryptKey value set) with firmware release earlier than 1.2.0 and that the phone needs to upgrade to release 1.2.0 firmware to use EncryptKeyEx to encrypt its configuration file.
To upgrade the phone, follow the same procedure as in Example 1, except set the EncryptKey value to the previously provisioned EncryptKey value (instead of to 0). In this way, the gkMAC_address file will be encrypted with EncryptKey as the phone expects. The phone can then begin using the gkMAC_address.x file encrypted with EncryptKeyEx.
New cfgfmt Tool
You use the cfgfmt tool to generate a Cisco IP Phone configuration file. Release 2.3 of the cfgfmt tool supports a stronger encryption method than the previous release of this tool.
The syntax of the new cfgfmt tool is:
cfgfmt [options] input-text-file output-binary-fileTable 7 describes the cfgfmt tool options.
