[OpenSER-Users] Problems with BYE

Hi, I made a pretty basic openser config with Sipwise but Im having problems when sending BYE to my upstream SIP provider. When I do a CANCEL it works but sending BYE the server doesnt forward any packets. Here's a ngrep of whats happening. My complete openser.cfg can be found at http://port53.se/openser.txt # U 99.88.164.203:30824 -> 101.12.20.26:5060 BYE sip:0709955324@bbr-ssw.sto.la.aa.net SIP/2.0.
