Cisco Cp-7937g Sip Firmware
Install the firmware required by the Cisco IP phones in the flash memory of the Cisco Unified Communications Manager Express systems. There are two commands required to provide access to these firmware files:
Cisco cp-7937g sip firmware
All the necessary firmware files for Cisco IP phones are stored internally in the flash memory of the Cisco Unified Communications Manager Express router, so an external database or file server is not required. During registration, Cisco IP phones use TFTP to download firmware files from the router's flash memory. All Cisco Unified Communications Manager Express configuration and language files are located in the memory of the router in the system:/its/ directory.
To make the firmware file(s) available through a TFTP server, use the tftp-server flash:firmware-file-name(s) command on the Cisco Unified Communications Manager Express router. The load phone-type firmware-file command under telephony service is also required to associate the model of IP phone with the appropriate firmware file(s).
The XML file SEPAAAABBBBCCCC.cnf.xml (where AAAABBBBCCCC is the MAC address of the IP phone) contains the call agent IP address and port, firmware, locale, directory URL, and many other pieces of information. This file is present when the IP phone has been added to the configuration.
Listing 7.8 shows a configuration file that contains the phone model (7931), IP address (10.6.150.1), and port (2000) for registering; the firmware filename; the language (English United States); and additional information for proper IP phone operation.
IP phones and devices that do not find the more specific SEPAAAABBBBCCCC.cnf.xml file can use the XMLDefault.cnf.xml file if they have never registered before and an autoregistration method has been enabled. IP phones that download this XML file through TFTP learn the IP address and port to send Skinny Client Control Protocol (SCCP) messages to when attempting to register. The IP phones also learn the version of firmware that is required to function properly with the Cisco Unified Communications call control product to which the phone is registering. Cisco IP phone models 7931 and 7961 are highlighted.

Cisco IP Phones use a TFTP server for its configuration files and firmware. A FreePBX module for managing TFTP server files has been created and available on the developers website, -06-06/freepbx-module-tftp-manager/ or from the FreePBX Trac ticket #1032
Version 8.12 is now released (29 May 2009)There are a few minor bugs fixed. (For Cisco Discovery Protocol (CDP), the VoIP capabilities bit is missing during initial boot)There is a guide to installing and updating to this firmware here: _7960G_IP_Phone_on_Asterisk.V8.12 Release Notes: _ip_comm/cuipph/7960g_7940g/firmware/sip_cucm/8_12/english/release/notes/796040sip_812.htmlV8.12 Download available at: graver/cisco/SIP-7960/P0S3-8-12-00.zip
Version 8.11 is now released (9 Feb 2009)There are a few minor bugs fixed. This version has correctly been loaded on an older 7960.There is a guide to installing and updating to this firmware here: _7960G_IP_Phone_on_Asterisk.V8.11 Release Notes: _ip_comm/cuipph/7960g_7940g/firmware/sip/8_11/english/release/notes/796040sip_811.htmlV8.11 Download available at: graver/cisco/SIP-7960/P0S3-08-11-00.zip
It appears to be impossible to upgrade directly from v3.x to v8.x (probably any version prior to v6.x), I had to upgrade to v6.3 first. It is very hard to find a copy of this the v6.3 firmware (not even on Cisco site). Search for P0S3-06-3-00.zip or get it at graver1/cisco/SIP-7960/P0S3-06-3-00.zip
Notes: This file is case sensitive in some firmware versions; all elements and attributes should be uppercase (except Tone) or the entries may be ignored. According to Cisco, the phone will always match the LONGEST expression. 350c69d7ab
