Hello, Our 500+ company is slowly moving away from our hosted conferencing solution to one I built a few weeks ago with Asterisk and MeetMe. When our Q3 conference call comes around, we will have the need to have approximately 300-400 users in this call. Obviously, all would be 'listen only' mode and only 1 or 2 two would be speaking as marked/admin users. Our conference hosting provider was able to stream our calls to the web so that lessened the number of calls into the bridge. I'd like to accomplish the same thing with Asterisk. I got Icecast and app_ices() up and working fine, streaming the conference, but I ran into three serious issues: 1. icecast only supports OGG/Vorbis and neither iTunes nor WMP can play that format natively. 2. A considerable delay of close to 45 seconds over the stream 3. Every x seconds, it sounded like a packet or two of speech was being dropped even though VLC reported no packet loss My work computer and the asterisk server are on the same network so network latency isn't the issue for #2 and #3. Has anyone successfully setup meetme streaming in the manner I have described? Were you able to stream WAV or MP3? Did you experience the 45 second delay? Cheers and T.I.A! -Matthew -------------- next part -------------- An HTML attachment was scrubbed...

The key was a helpful comment on the voip-info wiki. See this link: http://www.voip-info.org/wiki/index.php?page_id=991&comments_page=1#comm ent_41349.> 2. A considerable delay of close to 45 seconds over the streamThere is always a bit of delay when streaming audio from asterisk or any other source since both the sever client are doing some buffering. Not sure if there is a way to reduce this.> 3.

You could also embed the WMP object (I hate that so much!). My two (sightly off-topic) cents. -- Ivan Stepaniuk Alba Fot?nica S.L. www.albafotonica.com
