asterisk users - Apr 2007 - Too much silence, perceived delay

In a system connected to a verizon T1, Digium TE411P (quad T1 echo
cancellation), client is complaining it is "too quiet".

The complaint regards calls over the T1, not in house SIP only calls.

Their description indicates they want some earpiece feedback of themselves
speaking.  Also, they complain that it takes several seconds (3-4) for the other
party to respond.  That is kind of subjective, I guess.

Suggestions?

Have you been able to test this yourself? (Three to four seconds seems
inordinately long. That's as bad as a satellite link.)

Have you tried tinkering with the gain settings? Adjusting the gain can
impact sidetone, which might improve the call experience.

Are you seeing errors on the T1?

(A start, anyway)

There are different types of delay.  There is audio delay and there is 
dialing delay.  I suspect the users are complaining about dialing 
delays, rather than audio delays.

During conversation about this, both types of delay were mentioned.
