Hi,
When I use linphonec (3.3.2 or 3.3.4) in NAT mode, with different sip port to 5060, for example 49152. The call hang up on 36 seconds. I've captured the sip package with wireshark and I've observed that the NAT mode seems not working well.
My connection scheme is as follows:

I attach the ACK SIP package sent from router A to router B [We made in linphonec a call using the command: call
sip:address@hidden:49152]:
-------------------Wireshark capture-------------------
Frame 4061 (397 bytes on wire, 397 bytes captured)

In Dst Port: appears 5060 insteed 49152.
Does anyone know what could be happening?
