[Asterisk-Users] BAD/GOOD Echo Cancel

[Krystian Filiks]

Did you test the echo delay?
will 64ms be suffitient?

You can easily test the delay by recording the transmit and receive path 
to a sound file and using some sound editing software see how big the 
delay is.
That is how I did it when I worked for a Telco in Switzerland on theis 
TDM switch they had a big Echo problem on their SS7 links and PRI's
