Hi, I have not looked much into this, but I was under the impression that it's a client-side thing, as I read it the SDP contains various IP's for the media, the public (which the phone seeks out via STUN) and the private, the other phone tries to connect to each of those and the first answer it get's it uses for the media path, as a LAN should answer always faster than a WAN, it should create the mediapath directly between the two devices, therefore FS will not see the media and interacts only with the signaling. This is how I have interpreted ICE. Now, if it does not work this way I appologize, up to now I did not have any use for ICE as all our remote offices are small and they do normally not call each other and in our main offices our PBX's are (still) internal ...

At least not AFAIK. It also would require that both endpoints support it too, and not all do. In any case since FS is a B2BUA not a SIP proxy the endpoints are negotiating with FS not the other endpoint - so you're still going to want to detect that you want to (try to) bypass_media. -Steve On 11 January 2013 11:19, Raimund Sacherer < raimund.sacherer@logitravel.com > wrote: Hi, isn't there allready a protocol that does that? ICE? this is an excerpt from the SNOM wiki page (we have about 280 snom phones in action): --- snip --- ICE DESCRIPTION Choose whether or not you want to use ICE (Interactive Connectivity Establishment). ICE optimizes the media path. This would be the case, for example, when two phones in the same network are calling each other via a long media path through other, external networks. With ICE, the short media path in the same network would be chosen, which will presumably have better quality than the long one. Sometimes this feature will stop you from being able to make calls. When this occurs, switch it off. --- snip --- Link here: http://wiki.snom.com/Settings/user_ice Here seems to be more information, check "Probing Media Path": http://wiki.snom.com/Networking/NAT Best, Raimund From: "Chris B.

Usually phones are natted behind an ADSL router and using two RTP streams to speack each other (because, for example, are on different rooms on the same office) consume a lot of bandwidth. Is there anyone who has found a solution to this problem? I was thinking on using SIP INFO for sending DTMF (in case customer have to use some phone features activated via phone), using private IP (no STUN on phones) and keeping FS out of RTP streaming. Any help will be appreciated.
