Below is a list of cards and their current state of support with the FreePBX Dahdi Configuration module.

Please note some of these manufacturers require patches and changes to DAHDI for the cards to work. 

Some cards and manufactureres have gone through a Certification process, which means their cards are tested in-house and put under a load to make sure they perform.  If a card is marked as "Certified," that means it is officially certified for use in FreePBX and the FreePBX Distro.  If a card is marked as "Tested," that means we have tested the card and that it configures, but no other testing or certification has been completed.

If you are a manufacturer and want to get support or certification of your DAHDi Hardware please contact us

  1. Should we mention (in a separate section) also that developers added to DAHDI Config Module (at least since the release of 2.10.11/2.11.11...see Ticket 6244) HFC-S "Cologne Chip Designs GmbH" based BRI PCI (ISDN) cards support?

    I'm running FreePBX Distro 3.211.63-10 with an HFC-S ISDN "Cologne Chip Design GmbH" based BRI PCI card (ISDN) and calls from/to PSTN performs, AFAIK, very well.

  2. We only list Cards here that are supported and tested by us and that the manufacture has a working relationship with us.

    1. There something not clear on your answer or, eventually, on above lists. It's one of the two.

      What the status "Certified = No" and/or the status "Tested = No" does really mean when it's reported on some of (so listed) supported cards on above lists?

      I didn't wrote that HFC-S ISDN "Cologne Chip Design GmbH" based cards were fully (in-house) tested (under any type of load you can simulate) nor that they were thus certified...I wrote only that DAHDI Config, at some point in the near past, was updated to support the recognition of that type of (no brand, not so uncommon) ISDN BRI PSTN Cards.

      1. Certified means they are certified by the manufacturer to work in FreePBX. Tested means Schmoozecom put them in a sever and verified they work correctly. In both instances Schmoozecom does the testing. That's the point.

        Glad to hear your card is working though!

        1. Very interesting but I think you missed the point of my latest comment: your  type of reply leave me quite free to argue that above lists weren't written really for "Supported" cards at all...especially if a Card enlisted was labelled with "Certified = No" and "Tested = No" (There are some).

          The focus here is the meaning of the word "Supported" on this Wiki's page and, at this point, a question rises naturally: why to limit above lists with those brand names (only) if some of those Cards are still currently not Certified nor Tested?

          If a supported Card (=Certified AND =Tested) and an unsupported one (=! Certified AND =! Tested) both appear equally as "Supported"...isn't better for you to change the Wiki page's title to a less confusing/less pretentious "Some supported cards" (Joke)?

          Words definitely count. That's the point. (wink)

  3. Supported means the DAHDI module is designed purposely to support the card.  We will only add support for a card if we are adding other cards for a manufacture but at times we may not get a copy of every card they have.  That does not mean the card is not supported.  But we will not add a card from a manufacture as supported in the WiKi that does not provide most of their cards to us for testing.  Hence why we decipher what is tested and what is certified.
