<tt>Hi Nabeel,<br>
<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 class="de1">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 class="de2">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>

<div text="#000000" bgcolor="#FFFFFF"> <tt>Hi,<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>
Regards,<br>

<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. </div>
