Re: SIP/2.0 486 Unable to Comply in response to BYE

[Vladimir Ralev]

The unable to comply probably originates from freeswitch and the
reason for it should in the freeswitch logs. Most common reason for
this would be if you restart the freeswitch or the call was dropped in
some more obscure way. You must collect all logs to get an idea.

I discovered the issue about 5 minutes after posting it.  SIP ALG was inserting a "to" tag and disqualifying it from loose routing.
