Thanks.
Here it is the captured wrong ack I suppose.
One side is using linphone, the other is a Cisco gateway.
U 213.144.x.x:15394 -> 213.215.y.y:5060
ACK sip:[EMAIL PROTECTED]:53429 SIP/2.0.
Via: SIP/2.0/UDP 213.144.x.x:15394rport;branch=z9hG4bK1176333941.
Route: <sip:213.215.y.y;ftag=1627568967;lr=on>.
From: <sip:[EMAIL PROTECTED]>;tag=1627568967.
To: <sip:[EMAIL PROTECTED]>;tag=B27BADC-1420.
Call-ID: [EMAIL PROTECTED]
CSeq: 21 ACK.
Contact: <sip:[EMAIL PROTECTED]:15394.
Max-Forwards: 5.
User-Agent: Linphone-1.0.1/eXosip.
Content-Length: 0.
The other packets seem all right, at least for the rport header.
What I don't understand is that the problem appears
only when one side is using Cisco, with different clients
on the other side. From the captured ACK seems instead that the
bug is in the packet originate by linphone.
I can post the whole flow if it can be useful.
