> ========
> User A attached to the SIP proxy xxx.xxx.xxx.13 (Public IP)  calls to a GW
> xxx.xxx.xxx.11 (Public IP)  with several users  internally associated. In
> this case the user A can see the video and audio sent by the GW,  but the

> anything, why? maybe because the GW blongs to other domain (xxx.xxx.xxx.11

> If the GW calls to user A, it works fine (I can see the session in the
> mediaproxy with sessions.py)
>

> Scenario 2
> ========
> In this case, I have another GW with Public IP address xxx.xxx.xxx.14, but
> it doesn't include in the INVITE message the SDP body. The GW calls to the
> same user attached to the SIP proxy xxx.xxx.xxx.13 , and the behaviour is
> exactly the same as scenario 1, the calling site can sse the video and
> audio
> but the called can't.
> Unlike the previous scenario, the signalling is:
>
> INVITE without SDP  -->  200 OK (SDP)  -- > ACK (SDP)
>
> In theory, Mediaproxy 1.9.0  should support this procedure since it's a
> SIP
> standard mechanism, however the called party doesn't receive RTP stream.
> In
> my opinion, the problem could be related to scenario 1, I mean , the
> calling
> party is not attached to the SIP proxy (belongs to other domain) and when
> the 200 OK (SDP) message arrives to the SIP proxy, the mediaproxy doesn't
> do
> anything
