Thread: Fax with VoIP directly possible? with t38?

  1. #1

    Default Fax with VoIP directly possible? with t38?

    my internet/phone provider is switching to VoIP (=all-over-IP).
    that means that even if I use a Fax device attached to my router, the data is converted to IP anyway.
    I therefore conclude that it should be possible (in theory) to send faxes directly via software without dedicated fax hardware.

    is there such a software available for opensuse?

    I found t38modem with reference to hylafax. that seems to do it.
    http://software.opensuse.org/package...earch_term=t38

    had anyone been successful in implementing it?

    EDIT:
    looks like here it's done with t3modem / hylafax:

    I believe that if you connect the fax machine to the "new" phone line,
    the results are not good (timing issues, I think). In fact, they can be
    very bad.

    I have seen ideas that allow sending of facsimiles over IP using other
    protocols, but I have not experimented with it. Some people contract an
    external "fax relay" to do the job.

    There is a voip or telephony repo.
    I Have the impression I read about this stuff in the asterisk site
    documentation; I would have to dig it out from my notes somewhere.

    Hylafax via VoIP? Dunno...
