IP Phone 7965

[Adjara Group]

Hello,

We have several cisco IP phones 7965 which are working on SCCP Protocol, we would like to change firmware to SIP. I tired to do like Sreekanth Narayanan told in this discussion https://community.cisco.com/t5/ip-telephony-and-phones/change-from-sccp-to-sip/td-p/2769524 but without success, What do I need to change in xml file (SEP<mac address>.cnf.xm)?

Are the phones in CUCM or 3rd party call controller?

Thanks @Leo Laohoo for your reply,

Right now they are connected to the CUCM, but we would like to connect them to the 3rd party

If the phone is connected to CUCM, then the firmware will need to be set there.

If the firmware is going to be connected to a 3rd party call manager, the <loadinfo> tag will need to be updated.

Hello @Adjara Group 

What is the symptom ? You reser the phone and which state is not OK ? Does the phone download its SIP firmware ? etc..

[Adjara Group]

Thanks M02@rt37 for your reply, yes, we did reset like:

1. Unplug the power cable from the IP phone and then plug it back in.
2. While the phone is powering up, and before the Speaker button flashes on and off, press and hold the hash # key.
3. Continue to hold # until each line button (right of the LCD screen) flashes on and off in sequence in orange color.
4. Now release the hash # key and type the following sequence 123456789*0#

But when phone still boots as SCCP, what do I need to change in xml file(SEP<mac address>.cnf.xm)? 

[M02@rt37]

Ok @Adjara Group 

You just restart the phone I think.

Its need reset to download its new Firmware...

Do you see on the screen the firmware uploading ?

But where do I need to set in xml file new firmware name?

As your phone is connected to CM you don’t need to do anything in the XML file. Just remove the SCCP configuration for the device in CM and add it again as a SIP device. Then reset the device and let it load the SIP firmware. There shouldn’t be more to this. One caveat, make sure that you do not have auto registration enabled. If you do the device will auto register and a new SCCP configuration will be automatically added. Touching the XML file is needed when you don’t have CM or CME.
