Hi,
Not uncommon what you are seeing. Try playing with your echo can. type
Mark2 etc. on your analogue zaps also try tweaking your tx & rx
gain using ztmonitor to view your incoming levels. Analogue is def. a
lot more prone to echo than ISDN so get tweeking ; )
Cheers,

Our configuration is as follows:
SIP phones -> TE410P -> PSTN
When a SIP handset makes a call to other ISDN numbers - no problem.
When a SIP handset make a call to analogue numbers - echo.
I know for certain that the problem is at our end. Why?
If I call our Asterisk box via Disa and then place a call to one of the
problem analogue numbers (native Zap bridge) I don't get any echo. So
the echo seems to occur only when using a SIP handset and making a call
to an analogue number.
Can anyone provide a logical explanation for this?
