Hi.

So the idea is when i get in my proxy an 180 Ringing message , to play Early media on the one that initiated the INVITE in the first place. The 180 ringing is passing my onreply_route. In this case how can I extract the related session of caller and send him the Early media?
Also Daniel what is the difference of playing media to the UAC or the UAS? who is who?

in sip terminology, UAC is the one that sends the request and UAS is the one that sends the reply. However, some people do a mixture and consider uac being the callerand uac being the callee. Not using the funtion, I thought it might be easier to test both variants instead of checking the code.

Cheers,
Daniel

Thank you in advance

Hello,

the idea is to send the audio to the one that sent the INVITE, not
the one that sends the reply. So the respective SDP is not in
current processed reply, but in the request.

Not sure if is possible, though, I thought it is since you can
stream either to uac or uas.

Cheers,
Daniel

Guys,

I agree with Edson, maybe you are using the function on a
message that does not have an SDP. Print the METHOD and
RESPONSE to be sure you are not passing all messages through
the function.

It seems like a report/information and not a problem...

To be sure, could You please paste one call exchanged messages
captured with NGREP? Don`t forget to hide relevant IPs end
tell us
who is who... ;)

Dear all,

I'm trying to play Early Media instead of
Ringing WHEN
an 180
Ringing OR 182 Call Queue message is received
from the
destination UAC. In the onreply_route[1] I added the
following
lines in bold:

I use kamailio 1.5 and I have NAT enabled.

onreply_route[1] {
xdbg("incoming reply\n");
if ((isflagset(5) || isbflagset(6)) &&
status=~"*(180)|*(183)|(2[0-9][0-9])") {
force_rtp_proxy();
}
* if (status=~"(180)") {
rtpproxy_stream2uac("/usr/local/etc/rtpproxy/ast-ivr.alaw","");
} else {
rtpproxy_stop_stream2uac();
}*
if (isbflagset(6)) {
fix_nated_contact();
}
}

try rtpproxy_stream2uas(...) instead of stream to
uac function.

Cheers,
Daniel

When I get from a UAC an 180 Ringing does not
play the
media and
also in the syslog I see the following ERRORs:

Nov 17 14:11:29 YGOR /usr/local/sbin/kamailio[4681]:
