Description:For now i use the conference bridge for bridge 3 G722 channels in a conference. This works very well and gives no preoblems.

But when i add a ULAW channel into this conferenceroom the sound quality is lower on all the channels. Every channel use a 8bit audio channel.

My question: Can we decode all the channels to 16bit for a high quality sound between the G722 channels and a lower sound quality for only for the ULAW chanenl?

Also i try to transcode the ULAW channel from another asterisk PBX to an G722 channel and add this to all the three G722 channels. This doesn't work because the sound of the whole conference room is delayed after some minutes (sometimes more than 10 seconds).

This is an architectural issue with Asterisk, which is being worked on by The_Boy_Wonder (IRC, aka dvossel).

Please check with him if you're interested in this functionality.
