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.
