[Freeswitch-users] SIP Client couldn't receive BYE

[Florent Krieg]

Hello Jimmy,

Have you tried "sip_sticky_contact=true"?
(there's no documentation but here's the wiki page: 
http://wiki.freeswitch.org/wiki/NAT_Traversal#sip_sticky_contact)
I had kind of same issue as you and this solved my problem!
