SIP image on 7960 phone

I have some 7960 phones which use to work

with our SIP proxy server. A Call Manager is

on the same network. After upgrading the Call

Manager to version 3.1(2c) I notice that new

skinny phones which I wish to convert to SIP

no longer work.

On my SIP server I see the tftp load request

but I never see entries in the access_log or

error_log. Debugging flags for the various modules

are turned on and I use to see load messages in

these files. I can't figure out what happened.

The proxy seems fine.

What I have noticed is that the 7960 skinney

phones now have version information in their

firmware status menu where the previously

working phones did not.

I am not yet using the new version 3 SIP load

because I wanted to get the system working

before doing the upgrade. I am using POS30201


Can anyone explain what might be different?

It seems to be related to the phone getting an initial load from the v3.1(2c) call manager.

The problem happens if I move the phone to a

subnet without a call manager too.
