Hi All,

I’m looking for a PSTN Card that I can use with my Asterisk Server to achieve the following goal :

1. Detect FAX signal and route it to a specific extension.
2. Detect an incoming call from the same PSTN line and route it to IVR.

Do openvox FXO/FXS cards support this feature ? Is there any other brand that can be used with Asterisk and that is supporting this ?

Thanks in advance.

  • Perhaps use T38 instead? Would make your life a lot easier. (And you can use a T38modem software).

  • Fax detection is more of an Asterisk feature than the FXO card
    (although some cards have hardware detection). All DAHDI/Asterisk compatible cards should be able to detect incoming faxes (if enabled via their chan_dahdi.conf configuration). I have personally tested Digium, Sangoma, Openvox and Rhino cards and they can all detect incoming faxes and send them to the fax extension.
