<tt>So as far as I understand, you receive a request and you want
Freeswitch to route it back to OpenSIPS. There is no SIP mechanism
that can achieve this - you need to configure Freeswitch so that when
it gets a message from OpenSIPS, determine the gateway, and send
it back. Note that you need to set opensips's IP in the
destination URI, not the request URI, otherwise OpenSIPS will not
know the destination GW.<br>

<div>Hi,<br>
<br>
Generally there are three ways of doing this:<br>
<br>
</div>
1) Use SIP sever as an Edge Proxy (check rfc5626, should be
a quick read)<br>
</div>
2) Create spiral, route SIP call from proxy to your
media-server and then back to proxy from media server.<br>
</div>
3) Use SIP sever as a registrar and then forward registrations
to media sever and maintaining it. (cheap way though)<br>
<div>

the call hits the proxy and dispatched to the media
server. Media server makes the gateway selection and now
need to send the call to the provider. Instead of the
signaling to be sent directly from the media server and
the provider I and trying to pass the signaling back
through the proxy so the outgoing connections to the
provider will be seen by the proxy IP address not the
media server. Both the proxy and media servers are not

The add_path() function should

For sequential requests, you
