[Linphone-developers] Linphone-iphone(v1.6) not sending ACK to right destination when server behind NAT

[Coca]

Hello list,

I have a SIP AS running behind NAT ( Amazon EC2 indeed), and the call between linphone-iphone clients in this case always end up right after 36s.

After the packet capture I noticed that the ACK right after 200OK after the dialog establishment from the caller was sent to the internel ip address of the SIP AS.

What do you suggest in this issue?

Regards,

Coca
