As of late, I keep seeing a very odd error message in Asterisk and regardless of
how much debugging or verbose I set I can't get more detailed info to find
out
what exactly is causing the error. It's every few seconds and in no regular
pattern either.

Any advice on what I can do to get more information? I see it occur when
Asterisk doesn't think there are any active channels going on as well.
There's
a SIP device that is misbehaving somewhere. Most of the SIP phones are Polycom
IP600/601s.
