System has been working fine for many month.
Suddenly features like Call Forward, Conf call, reset from CCM or line modification from CCM don't work anymore.
Using wireshark , we've discovered that the callmanagers are not sending some skinny messages.
For example if you do reset or restart from CCM nothing is sent.
If you press CfwdAll the CM doesn't reply.
Placing and receiving calls still works.
We have a tac case open but they have been useless so far.
sr8a was applied to CM 4.1.3sr5b and phone load upgraded to the latest but still no go.
The database replication is OK and dblhelper shows no issues
Anybody seen something like that before?
