Re: [OpenSIPS-Devel] Using OpenSIPS/MediaProxy infrastructure with ICE enabled - looking for feedback
Additional note: I did not yet start my tests, but I already made some captures and gave a look at the SDP body generated by those snom phones allowed to use ICE. It seems that they are still doing ICE as proposed in draft-rosenberg-sipping-ice - and not as in the RFC-to-be mmusic draft. The new OpenSIPS/Mediaproxy enhancement does not have support for this legacy ICE variant, does it?

We support the current and latest version, the version that is going to become an RFC (is now in the RFC editor queue). http://www.ietf.org/id/draft-ietf-mmusic-ice-19.txt Depending on which previous version of ICE the device implement they may work or not only real testing can show.

Adrian Georgescu wrote: We support the current and latest version, the version that is going to become an RFC (is now in the RFC editor queue). Thought so. Depending on which previous version of ICE the device implement they may work or not only real testing can show. Unfortunately what they are doing looks more like the initial draft, as written by the sipping-WG: http://tools.ietf.org/html/draft-rosenberg-sipping-ice-01 There was also some post from snom on the sipping ML while alternatives and better strategies have been discussed. Then finally Rosenberg announced the new draft and explained the move: http://www.ietf.org/mail-archive/web/sipping/current/msg05449.html At this point snom probably decided to no longer go invest development time unless ICE is getting stable. And the following post (nearly two years later) let's me believe that their implementation is still the one it was at that time: http://www.ietf.org/mail-archive/web/sipping/current/msg08461.html I reported my thoughts to snom, waiting for feedback... In the meantime: thank you once again!

[OpenSIPS-Devel] Using OpenSIPS/MediaProxy infrastructure with ICE enabled - looking for feedback
Hello, We have enabled the latest OpenSIPS/MediaProxy versions with support for ICE negotiation on http://sip2sip.info We managed to obtain with our initial testing using Blink (based on PJSIP stack) directly connected RTP media streams between the end- points (by using the server reflexive candidates obtained from the STUN server) when setting the MediaProxy relay to low priority. If someone else has ICE enabled end-points, can test and provide us with feedback about the success rate of the ICE negotiation would be great to fine tune the software! The ICE functionality is described here: http://mediaproxy-ng.org/wiki/ICE Regards, Adrian ___ Devel mailing list Devel@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/devel
