    will the newer MD12 work with the old 1550 panels?

    Thanks. got it working. I think the problem was the customer kept
    answering the blasted phone. ;)

    Yeah, that will do it. From my experience, best to alert the customer to
    your incoming call(s).

    My biggest complaint with the DSC modem is the lack of a speaker, so you can
    tell exactly when to push the "recall" button in the software. Miss the
    timing, and you have to wait for the complete (usually 8 or so rings)
    sequence to call through...(or course, it doesn't help that I'm getting as
    deaf as a post....too many years in the shooting sports and 40 years of
    driving a motorcycle.....)

    I use a speaker phone on mute...it solves Napco issues as well.

    I had just got off the phone with them and told them I would be
    downloading their panel and they still picked up!? Can't complain too much
    the guy was in a bad wreck on a 4 wheeler last year. Was / is supposed to
    be dead.
    I must have a new md12 because I can hear the phone ringing at the other
    end.
    thanks again

    how can you hear if it's on mute? ;)
    I 'hear' you. I do the same for napco panels. On hook.

    Mute only keeps noise on your side from interfering with the transmission.
    You can hear the modem, and the full download exchange...comes in handy when
    trying to figure out connection problems...is it the modem? Or is the panel
    communication chip fried...

    Napco panels are extremely sensitive to outside noise...I spent many hours
    trying to figure out why certain Napco panels won't download unless I put my
    phone on mute...it could be too much line load, or low phone voltage...but
    why try to figure it out...just mute it and forget it...

    Ok, excuse poor attempt at humor.
    I'll keep that in mind if I have any trouble with napco in the future.

    Use ans machine bypass and ask your customer not to answer until he hears 3
    rings in a row. Count 2 secs after the first ring from the modem and hit
    redial.
