Hello. I have Asterisk 1.8.18 which connects to ISDN PRI. All phones are sip, Aastra 6757i. Everything works as expected. We also have a fax machine. We need to be able to use that FAX machine to send or receive faxes. We are planning to have a dedicated did for faxes. Before, FAX machine was connected directly to pots line.

Any digestions how to accomplish it?

    a) Without Asterisk: Get a ISDN-ATA (POTS-ISDN converter), e.g. DeTeWe TA 33clip, hook the fax machine to it and the ATA (configured to receive calls for the fax DID) to the ISDN line. At least thats how it would work with ISDN BRI, not sure about PRI. If you don’t have enough ISDN
    ports on the NT you could get an ISDN switch.

    b) With Asterisk: Get a SIP-POTS adapter, configure it with the fax DID
    and hook your fax machine to it. There are many adapters available:

    (FritzBox seems to be popular)

  • In addition to Markus’ suggestions you could also look at using iaxmodem and Hylafax. I’ve been using that for years and it works great. Once a fax is received it is emailed to whatever you configure. Sending faxes works too in libreOffice. If you have a bunch of DIDs you could give people their own direct line and fax number.

  • Hi,
     
    I am also looking for a fax solution. I use Cisco ATA adapter with fax machine and sending of fax works perfectly. But receiving fails after call is answeredby the fax machine. It may be a problem of the fax machine also. The configuration is simple. I use CISCO SPA 112 – 2 Port Phone Adapter. First connect an anlog phone to the adapter and dial the number given in the manual. You get an IVR menu to configure IP address.

    It’s been years since I set it up so I don’t know exactly how to configure it anymore. But I do remember that I found some howto/docs via Google so try that. And yes both Hylafax and iaxmodem are free.
