[Asterisk-Users] meetme mixer configuration

[Michael Jia]

Hi, Matt and Asterisk gurus

I encountered the same problem in my asterisk meetme.
Whenever the 3rd person joins the meeting, it creates echo in the meeting,
while 2 person meeting is fine.

I am wondering if you can give me more hint on how to configure the mixer to
have echo cancelled.
We are using analog phones connected to asterisk TDM cards.

Thanks a lot.
Michael






========================================
Hi,

Oops, my bad.

Turns out it was just mixer settings, feeding back through the
soundcard.  Sorry for the noise.

I'm trying to put multiple Linphones and Snom 200's into a Meetme room. 
 With two devices, echo is quite noticeable.  With 3 or more it 
degenerates into white noise.  Which part of the software is responsible 
for echo cancellation in a MeetMe room?  Is it a setting on the phones 
themselves, or within Asterisk?  And is this related to echo 
cancellation on the POTS lines?
