    4005AC + GD1370 + VoIp

    Tech had an issue with a fax board connected to a 4505AC. Machine has been in place pretty much
    since EBN came out. All of a sudden, it started showing on the TX log NO ISSUES. All transmissions
    show "OK", but the customer (school) said the receiving end, sometimes inside their network, sometimes
    outside, would receive the same document over and over again. Tech tried the obvious, blowing out the
    fax settings, reflashing the fax rom, reseating connectors. We were convinced it was something within the ATA settings or on their
    network. He spent time with their I.T. guy and they were at a loss. As a last resort, even though I thought it
    was a wild shot, we popped a new GD1370 board into the machine and it fixed the issue!
    I think it is the first time that I've had a fax board go bad, that wasn't a lightning hit
    (and that was back when phone lines were still attached to "MaBell". )

    Repeat receptions are a sign of poor phone line quality on the borderline between a failed transmission and poor image quality. If the sender identifies enough send errors it will send again. Sounds like VOIP to me. =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

      I agree. Protocol trace shows the entire transmission went perfectly. V.17 14.4k. EVERYTHING looked perfect. Only thing I can think
      of is the old board impedance was just enough different that the ATA box just wasn't hearing something. We asked their I.T. guy if
      he could pull something similar of a protocol trace and he looked at the tech like he said it in a foreign language. Asked if there
      were any data logs on the ATA or server and he had no clue.

        Try 1 & 3 Power On.

        325 to 7 (attenuation)
        335 to 1 (14.4 kbps)
        391 to 0 (ECM off)
        569 to 0 (V34 mode off)
        971 to 0 (Short protocol off)
        574 to 2 (Disable JBIG)
        200 to 1 (for PABX if on VOIP)
