[OpenSER-Users] Intial INVITES without SDP - sr-users

23 Jan 2008

Hi @ all,

I am fighting a pretty annoying problem at the moment.

As described in rfc3261 / 13.2.1 Creating the Initial INVITE

      o  The initial offer MUST be in either an INVITE or, if not there,
         in the first reliable non-failure message from the UAS back to
         the UAC.  In this specification, that is the final 2xx
         response.

My problem is the following:

I receive a initial INVITE without SDP, forward it to a PSTN Gateway.
...
 From the Gateway I receive the 200 OK with SDP offer.

In the onreply_route I make a call to the mediaproxy use_media_proxy();

Unfortunately use_media_proxy() seems to make a lookup command when used in a reply
route.

I would need to make a request command which would create the media session and then do a
lookup with the ACK from the
UAC.

Is there a way around this?

cheers,

Patrick.
