ISDN should make a sufficient difference in regards to echo. What echo canceller are you currently using for Zaptel?
I didn't even know there were choices. It looks like the default from zconfig.h would be used which appears to be ECHO_CAN_MARK3. I guess it would be nice if these were config options in the Zaptel port. Who are Mark and Steve and what do they know about echo cancellation?
Mostly it is OK, often the first 2 seconds of a call are awful and then it settles down. But sometimes the echo comes back from time to time during a call.
The other problem we've had is one of the TDM FXO ports getting wedged somehow and not answering any calls until a restart of the zaptel driver and/or whole machine. That happened about 2 or 3 times now over 6 months.
We are thinking of rolling this out to customers, who would not be happy with this level of reliability.
