[Asterisk-Users] Meetme versus app_conference

[Erick Perez]

Kevin, if I use ulaw for my sip users and my sip providers.... will i
minimize the "transcoding" hit to uncompressed mode to my server?

or will the load be the same even if I use g729 everywhere? Im trying
to optimize my setup as to do transcoding/uncompressing to a minimum.

However, app_meetme in SVN trunk (soon to be Asterisk 1.4) tries to minimize the amount of transcoding by avoiding the decoding of incoming audio from channels that are not speaking and by re-using the transcoded output for channels that share a format (codec). This should make it perform similarly to app_conference in many situations.
