Hello<br><br>I have a question regarding Asterisk echo cancellation.<br>I´m using a fax connected to an FXS interface and an E1 ISDN line to PSTN.<br>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.<br>
How can I know if the echo canceller is being cancelled when fax tone is detected?<br><br>Thanks!!!<br>
