Hi Daniel,

Thanks for this.

I took the entire config files and configured it as per my ips and ports, after doing that, still no call establishment(webrtc to classic sip phones and vice-versa). Following is what i get in kamailio.log:

rtpp_test(): rtp proxy <udp:127.0.0.1:7722> found, support for it enabled
ERROR: rtpproxy-ng [rtpproxy.c:1254]: rtpp_function_call(): unknown option ` '
ERROR: <script>: ==> duri=[sip:nudg.com:5060;lr;sipml5-outbound;transport=tcp]
INFO: <script>: Request coming from WS
ERROR: rtpproxy-ng [rtpproxy.c:1254]: rtpp_function_call(): unknown option ` '
INFO: <script>: Reply from softphone: 100

And this SIP message:
SIP/2.0 603 Failed to get local SDP.

Regards,

Abhishek

Hello,

the reply code indicates that the media type is not supported, thus there has been no gatewaying between webrtc and classic rtp. Just replacing rtpproxy with rtpengine is not enough, there are different parameters that have to be provided.

Searching on web, I see that Carlos has published a config for it, see:

Cheers,
Daniel

Hi,

I have successfully setup rtpproxy-ng kamailio module and mediaproxy-ng package on my ubuntu box. As suggested here:
http://kamailio.org/docs/modules/devel/modules/rtpproxy-ng.html

I have kept rtpproxy-ng's configuration same as the rtpproxy module, but still not able to connect the webrtc calls to classic sip phones (and vice-versa). Below is the sip message that is traced:

Can you please let me know, what's going wrong and how can i proceed.
