Linphone developers and user comunity,
I am using Linphone to connect to a Open
Video Communication/Telepresence (OVC/TPS) bridge from Cisco. This bridge houseTPS MSE 8710 blade v3.x. In this environment I want to make sure that we are able to interop with various SIP clients. I downloaded Linphone v3.7.0 and configured the client to use TCP/5060 and NAT. The client is able to connect to the bridge for approximately 50 secs. and then
disconnects. Using UDP/5060 and a STUN server is not an option. Adjusting NAT is also not an option. I am configured as TCP 5060, behind a NAT firewall.
The bridges sit behind Cisco Video Communication Servers (X7.2.3) which face the internet and use traversal licenses.
Linphone had worked prior to the blades being upgraded
to v3.x but has since stopped working. NAT is definitely issue in this case. According to Cisco, when the TPS re-invites for DTLS negotiation
(added in 3.x or higher of TPS) this is going to the wrong address because
LinPhone is populating incorrectly. In older versions of TPS we had
a bug where the Contact Header was not properly updating per RFC spec. Cisco
fixed that bug and now Linphone no longer works with OVC correctly.
I am being directed to Linphone for a fix or resolution to this issue. Is there something I can do here get the Linphone functioning once again?
Thanks,
Kendall
