[Freeswitch-dev] Automatic hangups?

Thu Apr 7 10:42:38 MSD 2011

Could you explain this a bit more? I don't understand how a bad gateway configuration in you FS server would cause your client to send ACK's to the wrong IP? Or am I missing something here?

Found it.

The "Gateways" configuration was wrong.  It was referencing the IP 
address of another server (TestSrv), so the ACK packets were getting 
sent to the wrong machine.  Very subtle bug -- other than the hangups 
things have been working ok, so I didn't suspect FS configuration to be 
the issue.

Found it by using WireShark to trace the SIP packets.

Thanks for the help, everyone.
