Echo on Digium Wildcard TDM410P

I have a FreePBX Distro 2.210.62-6 system with a Digium Wildcard TDM410P with hardware echo cancellation.

I have run FXO tune but I still have echo.

I have noticed that the /etc/fxotune.conf file has entries for all 4 of my channels but all the values are 0.

Here is the output of dahdi_cfg -vv

DAHDI Tools Version 2.6.1

DAHDI Version: 2.6.1
Echo Canceller(s): HWEC

Channel map:

Channel 01: FXS Kewlstart (Default) (Echo Canceler: none) (Slaves: 01)
Channel 02: FXS Kewlstart (Default) (Echo Canceler: none) (Slaves: 02)
Channel 03: FXS Kewlstart (Default) (Echo Canceler: none) (Slaves: 03)
Channel 04: FXS Kewlstart (Default) (Echo Canceler: none) (Slaves: 04)

4 channels to configure.

Setting echocan for channel 1 to none
Setting echocan for channel 2 to none
Setting echocan for channel 3 to none
Setting echocan for channel 4 to none

Probably best to contact Digium’s support department directly. They can be reached via
