Re: [OpenSIPS-Users] media proxy - B2BUA(signaling only)
Hi Richard, the solution I am using is working, but the header was useless, the
only problem is that a second media_proxy session is still opened, but this is
not an issue
#---> Force media proxy
if(search_body("c=IN IP4 1.1.1.1") && method == "INVITE"){
xlog("L_NOTICE", "***MEDIA PROXY FOUND [on another call
leg]\n***");
}
else{
$avp(s:media_relay) = "1.1.1.1";
use_media_proxy();
}

Subject: Re: [OpenSIPS-Users] media proxy - B2BUA(signaling only)
I'm having a problem that I think is the same as this discussion. When a call
from a natted user comes in to my opensips proxy, my config does auth and then
immediately fires up the nat ping and media proxy ( engage-mediaproxy() ) to
provide far end nat traversal. Now I'm trying to add top hiding from b2bua and
when the INVITE comes from b2bua back to opensips, the sdp has values from the
original invite rather than the mediaproxy IP and port.
I suspect that engaging the media proxy on the way out of the proxy rather than
on the inbound side will resolve this, although I haven't tried that yet.
However, this doesn't seem like expected behavior from the b2bua so I thought I
would chime in here.

Re: [OpenSIPS-Users] media proxy - B2BUA(signaling only)
Hi Bogdan,
I have found this logic that is working (tested), I think it will not create
problem as it is not possible for a new INVITE to already have the media-proxy
IP if is not already passing trought the proxy once.
#---> Force media proxy
if(is_present_hf("Media-Proxy")){
xlog("L_NOTICE", "***MEDIA PROXY FOUND [on another call leg]\n***");
}
else{
if(search_body("c=IN IP4 1.1.1.1") && method == "INVITE"){
#---> Tag the call, not to engage media proxy
append_hf("Media-Proxy: engaged\r\n");
}
else{
$avp(s:media_relay) = "1.1.1.1";
use_media_proxy();
}
}

Hi Julien,
Just a wild guess - maybe the mediaproxy does not work as you may invoke
it (request and reply) for different calls (for request on UA_A call and
for reply on UA_B calls) - afaik, both mediaproxy and rtpproxy use the
callid in order to bridge the request and reply SDP portsBut because
of B2BUA, you actually have 2 calls.
So, be sure you do both media setup steps on the same call (only on one
side of the B2BUA).
Regards,
Bogdan

Re: [OpenSIPS-Users] media proxy - B2BUA(signaling only)
Hi Julien, Just a wild guess - maybe the mediaproxy does not work as you may invoke it (request and reply) for different calls (for request on UA_A call and for reply on UA_B calls) - afaik, both mediaproxy and rtpproxy use the callid in order to bridge the request and reply SDP portsBut because of B2BUA, you actually have 2 calls. So, be sure you do both media setup steps on the same call (only on one side of the B2BUA).
