Public IP on what? The phone, or FS? Did you do a packet capture at the FS box, or at the phone? If you did it at the phone, it still doesn't prove that FS didn't send a bye.

At first I thought it was NAT issue so to isolate the problem I used a Public IP but I still get the same result? I have used wireshark to do a trace but I don't see FS sending a bye to A? Kindly advice me on how else could I solved this issue. On the NAT Part, I have enable RTP keep alive as well. Under RTCP, I have the keep alive turned on as well? Which other place are there setting I can configure with? Thanks in advanced Pedar for your kindest help Many thanks Simon Leck From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Peder Sent: Wednesday, September 07, 2011 1:57 AM To: 'FreeSWITCH Users Help' Subject: Re: [Freeswitch-users] - freeswitch bye issue It should happen automatically. Is A behind NAT? Sounds like a firewall/NAT may be dropping the bye. Also, have you done a debug on FS to see if it actually sends a bye or not to A?
