Cisco 7960 upgrade to SIP firmware

I bought one ip phone cisco 7960 on ebay it was with SCCP firmware. I use asterisk so need upgrade firmware.

Step by step.

1. Download and setup SolarWinds TFTP Server. It is free and works well.

2. Need SIP firmware from cisco site. I downloaded last version P0S3-08-8-00.zip . Unzip it to TFTP directory.

3. We need additional 5 files. I used notepad for it.

3.1 SIP<MAC adresse>.cnf

Example for two lines :

line1_name : 550 line1_authname : 550 ;user name registered in your Asterisk PBX line1_password : secret550 ;password registered in your Asterisk PBX line2_name : 551 line2_authname : 551 line2_password : secret551

3.2 SIPDefault.cnf

Example:

#Image Version image_version:P0S3-08-8-00 ; #Proxy server address proxy1_address: 192.168.10.1 ; proxy_register: 1;

3.3 xmlDefault.CNF.XML

Example:

<loadInformation7 model="IP Phone 7960">P0S3-08-8-00</loadInformation7>

3.4 RINGLIST.DAT

Example:

Piano 1 Piano1.raw Piano 2 Piano2.raw Pop Pop.raw Pulse Pulse1.raw Old Style ringer1.pcm Synth Low ringer2.pcm

3.5 dialplan.xml

Example:

<DIALTEMPLATE> <TEMPLATE MATCH="*" Timeout="5"/> <!-- Anything else --> </DIALTEMPLATE>

4. Copy all files to TFTP directory. As result we get 10 files.
5. Run TFTP server.
6. Erase cisco ip phone old config.

6.1 Disconnect network cable, power on phone.

6.2 Unlock configuration., go to settings-Network configuration-Erase configuration-yes

6.3 SaveCancel-Exit.

7. Unlock configuration., go to settings-Network configuration-TFTP server. Enter new TFTP server, Save-Exit.

8. Power off, connect network cable, power on phone.

As result you will see tftp server logs and your ip phone will get SIP firmware.
