[Asterisk-Users] Echo Problem with T411P

[Idris AVCI]

I forgot to mention one thing. I don't know if it changes anything.
Internal users are connected to another PBX which connects to asterisk
over SIP. Echo is always at internal user side. External user never
hears echo.

External User --> PSTN --> Asterisk --> SIP --> CIC --> Internal User

128 = 128 taps = 16ms of 8KHz audio, so no, not more that 128ms, but
definitely more than 16ms.
