[Asterisk-Users] Echo issues (again...)

[Andrew Yager]

Hi again,

I can now say that the info below has nothing to do with the echo 
issues.

I'm noticing a new connection too - it seems that numbers are being 
left out of the dial at times. It's on those calls especially, that I 
see echo. (The exchange answers and tells me the number isn't correct 
and to try again). Perhaps * dials too soon and interrupts the echo can 
doing it's training?

Thanks,

A
