Hello,

I have an AAH-1.5 with a TMD400P with four lines, 8 Grandstream GXP-2000 phones, I am having echo issues on the GXP-2000 side.

Here is what I have tried so far:

The server has everything in the bios turned off except what is needed, USB, LPT, Serial etc,etc.

I have uncommented Echo Suppresion in zconfig.h and shutdown and turned back on the asterisk box.

I have updated the phones to 1.0.12 firmware, I have echotraining=800, echocancel=yes, echowhenbridged=yes, in my sip.conf file. I am using Mark2 as the echo suppresion and still I have echo.

Is this correct? I do not believe having these echo parameters in sip.conf will achieve anything.

They should be at the top of zapata.conf.

Regards,

Richard
