[Asterisk-Users] Echo cancellation again ...

[Tom Hayden]

I have experienced pretty nasty echo on my PRI w/TE110P. The echo was
only coming from other POTS lines, because cell phones already have
echo cancellation, and other PBX's had the same.  I resolved the
problem by turning on the AGGRESSIVE option and it works fine now, and
we haven't noticed a severe degradation in sound quality - most of my
operators were just happy the echo was gone :)
