Hi, i have one installation with the following issue:
Asterisk ABE-B.1-3
Polycom Phones (tryed different firmware releases)
the phones unregisters randomly, i do trace with tcpdump and analyse with wireshark and saw that when phone sents something that is not in the asterisk dialplan something weird happends… signaling traffic start to flow at a high speed and after a while phone unregisters.
I think that it’s some asterisk issue.
This is a little of that captures:

As you can see it’s an infinite loop. it solves restarting the phone or restarting asterisk.
