Zaptel message

Asterisk Asterisk Support
1

I keep seeing the below messages when I look at DMESG:

zaptel disabled echo canceller because of tone (rx) on channel 1
zaptel disabled echo canceller because of tone (rx) on channel 2

and so on.

I have Asterisk interconnected to another type of switch using the PRI cards.

Any idea why this displays? I am using a Digium TE212P card.

Just as a guess you can try tweaking the gains. Also try asking on the users list lists.digium.com

It’s picking up a fax tone or thinking it’s getting a fax tone. Uncomment this line in zconfig.h in your Zaptel source and recompile and reload your kernel modules:
/* #define NO_ECHOCAN_DISABLE */

Hi
As Angler has said its because either fax or Modem tone has been heard on the line.

Personaly leave well alone. you dont want echo cancelers on data calls.
Are you getting any other problems ? or is it just you are seeing the message.
