<tt>Hi Sanjeev,<br>
<br>
As I understand correctly, you end up connecting into your
opensips devices from different networks - a devices from the
private network (same as opensips) and another device from the
public network.</tt><br>
<tt><tt> But note that bidirectional direct communication between
the 2 devices is not possible, as the public device cannot send
traffic to a private IP/destination.<br>
</tt>Depending on the opensips cfg, the SIP signaling works, as
OpenSIPS will act as a bridge between the 2 networks. But this is
not true for RTP, as RTP goes directly between the 2 devices. So,
what you need is to use a media relay acting a bridge between the
2 networks.<br>
<br>
Regards,<br>

<div>Hi ,</div>
<div><br>
</div>
<div>i am new to opensips world and i installed the openSIPS
version 2.2 , facing issue of media. Setup is my configuration
is like </div>
<div>1) UAC request come through fortigate firewall on public
address (<a class="moz-txt-link-abbreviated" href="mailto:1234@49.121.121.121">1234@49.121.121.121</a>) and then passed to my opensip
machine (centos 7 , opensip version 2.2) having local address
( natted with public address) </div>
<div>2) registration of UAC is fine and if UAC are on same
network lets say one client on my laptop and another on mobile
device (both on same ISP WIFI) then voice is going through
between the UAC but i switch the network of the mobile to
telco service provider then their is no media pass on in
between the UA or some time only one UA able to listen the
other side.</div>
<div><br>
</div>
<div>i looked online and search lots of stuffs related to this
and changed in configuration but unable to solve or find what
and where i am getting. i tried TCP dump for both kinds of
call i.e having voice or no voice but unable to identify the
difference between calls having voice and no voice.</div>
<div><br>
</div>
<div>Since i am new to this setup and configuration , just stuck
due to above problem .</div>
<div><br>
</div>
<div>Please suggest where to look and what could be the possible
reason. Currently all traffic ( i.e all ports open) being
allow from firewall to machine </div>
<div><br>
</div>
<div><br>
</div>
<div>Thanks</div>
