[Asterisk-biz] PRI and echo cancelation ...

[Michael Blood]

That is interesting,  do you know how they are able to convert the digital
signal to analog (pri to pots) without an echo?  
I have never had a problem on any lines where the telco does conversion.

As far as I can tell most local telcos don't do echocan on for local calls.
