> 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?
