[hylafax-users] HylaFax / Asterisk Not Handling Incoming Faxes Correctly?

["Ben Blackmore" <bjblackmore@xxxxxxxxxxx>]

Hi,

 

I'm using PBX in a Flash, Asterisk 1.4.21.2, FreePBX 2.7.0.2 & HylaFax 4.4.4

 

I have a single POTS line that we rarely use to send/receive faxes on (maybe once every couple of months to open credit accounts). We've now configured this line to act as a fail over to our SIP trunk - again it rarely goes down, but we want this 'just in case'. Because of this, it's not worth paying for 2 separate lines, so we're going to use the single line for both fail over & faxing.

 

I've installed an X100P FXO card, and configured Zaptel on the server. I can make and receive calls using the FXO card. I now want to configure HylaFax to send/receive faxes. I've followed the instructions in 'HylaFAX / AvantFax for PIAF! - Parts 1-4' (http://www.pbxinaflash.com/forum/showthread.php?t=3645), and can successfully send faxes. However, when a fax comes it, it just seems to ring internal extensions. I've set the inbound route (in FreePBX > Setup > Inbound Routes), to detect faxes, type zaptel, detect time 4, and send to Custom Destination: Fax (HylaFax), but the internal extensions still seem to ring on incoming faxes. If I change the default destination for the inbound route from Ring Group to Custom Destination: Fax (HylaFax), then the fax does go through to the AvantFax inbox, and is received correctly, the trouble is, normal calls also go though to the AvantFax inbox, and the caller gets the squeaky beeps & tones! It seems Asterisk/HylaFax can't distinguish between voice & data calls?

 

Can anyone tell me how I can get Asterisk/HylaFax to receive fax transmissions, and send them to the AvantFax inbox correctly, while still receiving voice calls, and putting them through to internal extensions?
