Quick question. Under the latest 1.2.4 Zaptel/Asterisk. Is there anything that needs to be configured for Zaptel to take advantage of the hardware echo cancelling feature of the TE411P? Do I still need to configure the aggressive echo canceller and MARK2?
Thanks,
I am curious about this as well. I currently have the echo cancelling in zapata.conf commented out and I get echo when the TXGAIN is on 0.0. When I turn it down to -14.0, the echo goes away.
ASFAIK, if you enable echocancel and you have hardware echocancel, the drivers will use the hardware and never use software echo cancellation.
And decrementing the TX Gain is one of the ways to take away the cause of echo (crosstalk) buy lowering signal levels.
