You should put something between answer and dial, to let * have time to
get the fax tone: with your dialplan, the call is immediatly bridged to
SIP/3000, so no fax detection happen at all.<br>
A thing like:<br>
<br>
exten => s,1,Answer<br>
exten => s,2,Playtones(ring)<br>
exten => s,3,Wait(3) ; if fax tone comes here, * should jump to fax extension<br>
exten => s,4,StopPlaytones<br>
exten => s,5,Dial(SIP/300....<br>
<br>
exten => fax,1,......<br>
.....<br>
<br>
Hote This helps<br>
