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

Again, I know Sangoma is a sore subject with some on this list, but the

not Sangoma specific, although it did include some research into
different hardware/software based cancelers.
I put a Tellabs 64ms echo canceller into my facility this weekend and
am praying that it removes are echo problem. If it does, I plan on
making it a standard on my Asterisk installs that have a channel bank
or T1.
