[Asterisk-Dev] HELP: BYE-request not sent to SIP-peer

[Josh Roberson]

Roland, It would have been nice to post a followup :P

A few of us took a crack at this on IRC, and have decided that the real 
problem here are the contact headers being set by the provider, and * is 
not at fault at all, since we honored the contact headers.   Many thanks 
to pfn, as he pointed out the providers headers were wrong, and asked 
Roland to set nat=yes, which solved the issue temproarily.
