Firmware Upgrade issue - 7962G from SCCP42.9-3-1-SR1-1S to SIP

[Suvenduji]

Dear Experts!!

This is my first query on this forum.

I am trying to upgrade a brand new Cisco 7962G from SCCP42.9-3-1-SR1-1S to SIP 8.5.3 or 8.5.4.

I am not using UCM and instead using TFTP server.

In the past (approx. 12 months back)  I was able to upgrade the 7962G phones to SIP 8.5.3 but the new phones complain with an error "Load rejected HC". I tried to upgrade it to a higher version 9-3-1SR3-1 but the proxy ports are showing null values and not able to register with my SIP registrar (3rd party non-Cisco).

Is there any change on the new 7962G compared to the previous ones available a year back?

Any advice would be great help.

Many thanks in advance.

Regards,

Suvendu

Yes, there has been a hardware change on some devices which forces the use of later versions of firmware.

See this Cisco document:

Hi Nishant/Gordon,

Thanks for your responses. I managed to upgrade the firmware from SCCP to SIP.

However, Proxy Port on my phone is empty and possibly as a result of this it's not sending any SIP registration messages. Register with Proxy flag is set to True and SIP Line is configured with extension and proxy IP.

Please see the phone information I retrieved from the phone post upgrade.

Am I missing something here?

Please note, I am not using Cisco UCM. I am trying to register the phone with a 3rd party SIP Server.

Upgraded SIP firmware version is - SIP42.9-3-1SR4-1S

Thought of adding these points which might be helpful to make any suggestion.

Dear Gordon,

As per my previous post, I managed to upgrade the firmware to 9.3.1 (SIP42.9-3-1SR4-1S) based on your/Nishant's input.

However, my phone is not generating any SIP registration messages. Line1 and Line2 are configured with correct SIP server IP details however SIP proxy port is empty. Register with proxy flag is set to true. I am trying to register with a 3rd party SIP proxy.

Seems new 7962G won't allow you to change the SIP proxy port via Phone Settings.

I am using below SEPxxxx.cnf.xml file configure the phone line. Anything wrong here?

Please advise. We are stuck with lots of new phones where as all OLD phones are working fine.
