<font face="monospace">Hi,<br>
<br>
OpenSIPS listens on 5060 for incoming TCP conns, but when
connecting (to other server) it uses a random / ephemeral port as
source of the outbound TCP conn - this is normal, how TCP works in
most of the cases.<br>
<br>
When OpenSIPS is not able to connect anymore, do you see any
errors in the logs? <br>
<br>
Regards,<br>

<div>Here 172.x.y.z is my opensips server and others are gateway
IPs . I can understand the TCP connection from the 5060 port
. </div>
<div>How do opensips select other ports here ? </div>
<div>Is this the default behaviour of opensips ? Or in the
latest version the behaviour changes ?</div>

<div>Hi , </div>
<div><br>
</div>
<div><br>
</div>
<div>I have a server running on opensips 2.2 version (Yes
that is very old I know , we are planning to upgrade that
in near future ) . </div>
<div><br>
</div>
<div>On that server I have set up the gateways with TCP
socket connection . Openisps while sending outbound calls
to the gateway give the call in TCP . </div>
<div><br>
</div>
<div>From the last 2/3 months we observed , randomly
sometime in 7days or 10/12 days the connection won't get
established and calls get affected . </div>
<div><br>
</div>
<div>Once we restart the opensips service things start
working fine . So here is opensips blocking something ?
or is it on my linux machine blocking the connection ? </div>
<div><br>
</div>
<div>For the proto_tcp module I have not configured any
parameters . just loaded the module . I am hoping the
default values must be in use . </div>
<div><br>
</div>
<div>Can anybody suggest to me what I need to debug here ?</div>
