Chapter 3 Managing Cisco SIP IP Phones

Modifying the Phone’s SIP Settings

Before You Begin

•Ensure that you have downloaded the SIPDefault.cnf file from CCO to the root directory of your TFTP server.

•Review the guidelines and restrictions documented in the “Configuration File Guidelines” section on page 2-6.

Procedure

Step 1 Using an ASCII editor, open the SIPDefault.cnf file and define or modify values for the following SIP parameters as necessary:

•image_version—(Required) Firmware version that the Cisco SIP IP phone should run.

Enter the name of the image version (as it is release by Cisco). Do not enter the extension. You cannot change the image version by changing the file name because the version is also built into the file header. Trying to change the image version by changing the file name will cause the firmware to fail when it compares the version in the header against the file name.

•proxy1_address—(Required) IP address of the primary SIP proxy server that will be used by the phones. Enter this address in IP dotted-decimal notation.

•proxy1_port—(Optional) Port number of the primary SIP proxy server. This is the port on which the SIP client will listen for messages. The default is 5060.

•tos_media—(Optional) Type of Service (ToS) level for the media stream being used. Valid values are:

–0 (IP_ROUTINE)

–1 (IP_PRIORITY)

–2 (IP_IMMEDIATE)

–3 (IP_FLASH)

–4 (IP_OVERIDE)

–5 (IP_CRITIC)

The default is 5.

•preferred_codec—(Optional) CODEC to use when initiating a call. Valid values are g711alaw, g711ulaw, and g729a. The default is g711ulaw.
