Hi,

"zap show channel 5"
To see channel 5 specs, and take a look at "Echo Cancellation: 128 taps unless TDM bridged, currently OFF" during calls, you must have "ON".
If you have hardware echocan module, as for TDM2400E, you must also read
"DSP: yes" if this module is active.

Best Regards,
Francois BERGERET,
France.

Ok, but is there  a way to check if echo cancellation is active on a call in progress ?

Thanks

Giordano

Echo cancelling is only enabled if there is a call in progress.
