[OpenSIPS-Users] Linphone and OpenSIPS over TCP

[Nabeel]

Hi Bogdan,

Even if I remove the 5 second timeout by removing #modparam("tm",
"fr_inv_timeout", 30), the timeout occurs after about 20 seconds. What do
you suggest is the solution?
Hi Nabeel,

Your OpenSIPS tries to connect via TCP to the destination and to avoid
blocking it is doing it async:


Feb  1 19:22:13 server1 opensips: Feb  1 19:22:13 [20587]
DBG:core:print_ip: tcpconn_new: new tcp connection to: 188.29.165.162
Feb  1 19:22:13 server1 opensips: Feb  1 19:22:13 [20587]
DBG:core:tcpconn_new: on port 58985, proto 2
Feb  1 19:22:13 server1 opensips: Feb  1 19:22:13 [20587]
DBG:core:proto_tcp_send: Successfully started async connection

After that, in 5 seconds, the final timer hits (as timeout for no reply),
while the TCP connect still haven;t finished (so there is no actual packet
sent out).

Hi Bogdan,

Below is the requested log for TCP call attempt.  User 1111 is trying to
call user 2222 via OpenSIPS server 162.248.6.120 :
