[asterisk-users] Star Wars Echo Sound

[Rob Schall]

Actually, its just the opposite... The call is okay for a few seconds,
then the odd echo kicks in. When the training isn't turned on, it takes
20 seconds to so to kick the echo. With the training on, it works great
except for this bug. Several of the people using the same * system but
different phone stations are not seeing this problem.

I saw someone else believed it was a softphone issue. Is it possible
that its not a sangoma problem, but rather a polycom 501 issue? I just
want to start putting the grind to the correct people.
