I have a SPA8800 which has 4 x FXS & 4 x FXO ports.<br>
<br>
It took me some time to produce a working configuration.<br>
<br>
In Asterisk I have the following where 904 is the extension of the fax-modem and itsp is you VoIP Service Provider.<br>
<br>
sip.conf<br>

I am including information from my SPA8800 for one of the FXS ports I have a Fax Modem attached to, the key to getting it to work I believe is the "FAX Tone Detect Mode".<br>
