[Asterisk-Users] echo cancellation

[Steven Langley]

Hi there

I am using asterisk version 1.2.4. I have clients based on the iax client
library dialling into meetme sessions. I am experiencing echo in the case
where one or more users has speakers instead of headphones. So the audio
from me is fed from the other participant's speakers into their mic and back
to me.

What is the best way to fix this? Is there an echo cancel facility in
asterisk which will sort this out?

Many thanks

Steven
