Hi, So I findally got some time trying WebRTC. I noticed that some clients has no media when using WebRTC. I using the latest master with jssip 3.0. While my chrome(30.0.1599.101) has no problem all the time, other chromes elsewhere seems has no luck. e.g. 31.0.1650.63 and 33.0.1737.0 canary. I listed 3 channels below, looks like only my channel has 'AES_CM_128_HMAC_SHA1_80' and other channels has no that and no media. Also I see no auto stun for a long time from the log. Before trying more, is any hint it's a Chrome version problem or anything else? the no audio stun for a long time log has anything related to the client or only related to server side? Any configurable params? Thanks.
