<tt>The problem is not the 5 seconds timeout at sip level, is the
fact that the end point you are trying to connect to via TCP does
not accept the connection. You can check that via tcpdump.<br>

Your OpenSIPS tries to connect via TCP to the destination
and to avoid blocking it is doing it async:<br>
<br>
</tt><br>
<div>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</div>
<div>Feb 1 19:22:13 server1 opensips: Feb 1 19:22:13 [20587]
DBG:core:tcpconn_new: on port 58985, proto 2</div>
Feb 1 19:22:13 server1 opensips: Feb 1 19:22:13 [20587]
DBG:core:proto_tcp_send: Successfully started async connection<br>
<br>
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).<br>
<br>

<br>
I strongly suggest to look into the opensips logs
and see what opensips try to do with the call.
Based on your saying (that you see a timeout), I
suspect your OpenSIPS tries to deliver the call
over TCP to a destination which does not listen on
TCP.<br>
If you do not know hoe to interpret the logs, run
opensips in debug=4 mode, upload the logs
corresponding the INVITE execution and provide the
link.<br>
<br>

TCP still does not work. My initial request

can call using TCP with OpenSIPS listening

<div
style="font-size:12.8px">There
seems to be a problem with
calls over TCP using
Linphone, and since
Linphone is a popular open
source application, I
would like someone to
please verify this
problem. Calls work fine
with Linphone over UDP,
but after registering with
TCP using the same
credentials, calls do not
connect at all and lead to
a request timeout. A
request timeout does not
say much about the cause,
but in this case I suspect
there is something wrong
with TCP on the server
side. I would like someone
to please install Linphone
on your phone and connect
to your OpenSIPS server
using UDP and TCP. Please
report here if the calls
work over both transports.
