    I found a reason to use 4/2, sending on a VOIP line. Sometimes it works with
    some equipment and doesn't with others

    Don't even try 4/2 express, since it is similar to Contact ID it usually
    won't work either

    Mark, have you tried downloading the panel ? Does it handshake properly ?

    The one installation with VoIP I have uses 4/2 but it's "iffy" about
    connecting with a remote modem...

    Great ! I'll be very interested to see how things work out for you. In the
    meantime, I'm going to take the advice mentioned by several people on the
    newsgroup, to caution clients about hooking up alarms through VoIP. Until
    things are clarified fully, I'm going to simply recommend they don't do it.

    Had both of those today, the first was an Ademco Vista-10SE over Comcast
    cable in Atlanta, downloaded okay but sporatically sent Contact ID signals,
    switching it to 4/2 seemed to do the trick on that one

    2nd was a DSC 1555 v2.3 over a dish VOIP setup (not sure yet the specifics).
    That one sent garbage if using CID, with SIA sometimes sent okay but most of
    the time more garbage and 4/2 wouldn't work at all, the tech mentioned he
    was hearing echos so I think a DSL filter might fix that, if not then he's
    going to have to go with cell as the primary. Couldn't download that one,
    the panel would pick up then get cut-off for some reason, it was wierd.

    This is the ISP provider of the home the DSC panel was on

    Previously did a Vista-10SE over Comcast cable here in Dallas with no
    problems at all. I guess it all depends on the network

    Since the PC is after the VOIP it shouldn't matter in fact it could be
    turned off and the VOIP will still work fine

    Regardless of how well it works I still wouldn't recommend using VOIP
    without cellular backup, too many things can go wrong with the phone service

    And the fact that lately I've been quite a few seeing Vonage outage stories
    on the web
