asterisk users - Jul 2012 - echo canceler query

Hello

I have a question regarding Asterisk echo cancellation.
I?m using a fax connected to an FXS interface and an E1 ISDN line to PSTN.
The issue I?m having is with sending fax through the E1 and I?m suspecting
is due to echo troubles as I have some echo issues in my E1 line.
How can I know if the echo canceller is being cancelled when fax tone is
detected?

Thanks!!!
