Cisco 7960 Phones

So work has all these Cisco 7960 phones (ever see 24?) that are sitting in a box. Here are instructions for installing the SIP image and getting rid of the annoying SCCP image.

Overview

The Cisco Phone ship with Cisco’s propritary voip protocol “Skinny” aka SCCP. To be useful the cisco phones need a SIP image installed. This is done by tftping the sip image over.

Process

Setup DHCP and TFTP server

This is what I put in my dhcpd.conf:

# Don't use screwed up ELNK DNS. Use Room17 instead.
option domain-name-servers 82.103.135.68;

subnet 192.168.3.0 netmask 255.255.255.0 {
  range 192.168.3.10 192.168.3.250;
  option routers 192.168.3.1;

  next-server 192.168.3.1;
  allow booting;
  allow bootp;
  filename "pxelinux.0";

}

The cisco phones will assume the dhcp-server is the tftp server. While there is an option to change this, I’ve yet to make it work. Just easier to install atftpd on the dhcp server.

Install atftpd. Others might work, I use this one. No config needed under SuSE Linux. The rest of this document assumes /tftpboot

Install tftpboot files
You will need:
* Cisco firmware for 07-04-00
* Cisco firmware for 08-03-00
* XMLDefault.cnf.xml
* dialplan.xml
* RINGLIST.DAT
* SIPDefault.cnf
* SIP-flash.cnf
* syncinfo.xml

Unzip 08-03 first. Then overwrite with 07-04. 07-04 has the working bootloader, 08-03 has the latest SIP firmware.

ln -s SIP-flash.cnf SIPMAC-ADDR-ALL-CAPS.cnf 

Boot the phone
“*”, “6″, “Settings” is the ctrl-alt-del equlivant.

This is what you should see is syslog if *.* is enabled (comments in **):

Not all of those files will exist. In fact you need to make sure the CTLSEP* and SEP* files DO NOT exist, else it won't attempt to download the SIP* configs.
