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
load.
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.
