Newbie with Digium TDM410 + Asterisk

I have installed everything following the document and ebook.
I got 1 FXO on Channel 1 and 1 FXS on Channel 3.

ZTTOOL report that there is No Alarm.

I have setup the extension to Answer the call and Echo what it hear.

However, Asterisk did not pick up the call when I ring it by other phones.

How can I trace the problem or how to make sure the hardware is working?

Thanks,
Marquis

post your zaptel.conf, zapata.conf, extensions.conf and the output from “asterisk -r” while placing the call
