Hi Daniel,
I was able to solve a fraction of my problem, Actually, the github link had
used rtpengine.so and i was using rptproxy-ng.so, there is a difference in
the flag conventions between the two; i modified that to achieve a little
progress.
Now, i am able to call on webrtc(firefox) from sip phone. However, after
accepting call, there is no audio, and disconnecting the call from either
end does not disconnect the call.
When i try to call from webrtc(firefox) to sip phone, there is no
signalling at all, and the sip phone to webrtc calls can't connect after
that. (I analyzed that mediaproxy-ng/rtpengine process terminates and has
to be started again)
Following are the links to my latest kamailio.cfg file and port trace log
of sip messages.

I am clueless at the moment!
Regards,
Abhishek

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

And this SIP message:

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:
SIP/2.0 488 Not acceptable here.

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