Hi,<br>
I need to pass modem calls through a TDM400 card. Conecting the modem
to the FXS port (ZAP/1), it should be put through the FXO port (ZAP/4)
directly.<br>
Even though Echo cancellation is disabled in both lines the call is
never successful. Modems speak for some time and then the line is hang
up with the message "No answer from remote side". I send thereafter
some traces in case someone is interested.<br>
<br>
I know modem calls are not easy as something is messed up in the
signaling going through asterisk but has someone been successful in an
easy configuration such as this one?<br>
<br>
Thanks,<br>
Jose<br>
