Dear Kurento community,

I 've just release first version of a simple simple WebRTC to SIP Gateway : https://github.com/daimoc/Kurento-SIP-GW
Has some people are trying to do this since few time, this code can be a good start to learn how to plug a sip stack with Kurento client in nodeJS.

This gateway is made with the good drachtio library (https://github.com/davehorton/drachtio)  for SIP signaling and Kurento for the Media Server.
And of course, it works in calling Asterisk PBX Dialplan.

Regards,
Damien

Didn't try it yet, but this looks great! I have no experience yet with drachtio. For our implementation of a WebRTC to SIP GW we used sip.js which we extended with a UDP and TCP transport.

Quick question; in the readme of the Github project you mention adding DTMF support (soon). This is something we're looking into as well. We support INFO methods. Which of the DTMF standards are you targeting (RFC2833, INFO, in band)? And how or you planning on implementing this?

Best regards,

Tom

Hi Tom,
Thanks for sharing your experience on sip.js transport modification.
It could be a good solution to try later to reduce external dependency.

I've just commit an implementation of DTMF sending over SIP INFO like supported in Asterisk.
And I'll try to play with in band DTMF and maybe RFC2833 if it's possible to implement it on Kurento.

Regards,
Damien.
