    In order to connect VOIP network I need at least :

    1) PC 386 or more
    2) Sound card, full duplex capabilities.
    3) network connection

    these have to be present in 2 machines.

    And to connect to the internet I need some kind of hardware accelerating cards like Quicknet PhoneJack or LineJack.

    My Question is. Is it possible to have the above and using a voice / fax / modem instead of using a phoneJack card.

    Simple answer is no.

    Detailed answer is that voice/fax modem is not the same as PhoneJack. The Phonejack is essentially a sound card, with the G. protocol drivers built into the hardware. With the analog to digital conversion happening in hardware, it is *much* faster than in software. This reduces the delay due to slow software conversion and dramatically reduces the tiem to get your voice to the other party; less lag.

    However, with a full duplex sound card, you can skip the Phone Jack AND modem altogether and just do the VoIP in software, like NetMeeting, etc.

    Other interesting note is that the software has to be written to take advantage of the PhoneJack driver capabilities, so PhoneJack with Netmeeting is pretty much the same as with a full duplex sound card. The hardware embedded protocols don’t get used unles you use the Internet Switchboard software from Quicknet, or Net2Phone and their driver.

    Hope that helps.

    It is possible to use the phone jack or linejack to make call using other compaines such as Net2phone etc.

    Yes, it is possible, but you need to find an old copy of their switchboard software. The newer one forces you to us Microtel – which is their service that resells other providers.

    Older versions of the software allow you to put in your Net2Phone account # and password.

    Note however that some features and advances made in the newer software you won’t be able to use. What I actually do is use the newest driver with the old software. Works like a charm (so far).

    How do you connect a proprietary voice card to somone on a LAN whose PC is running netmeeting.
    I have the C sample codes to connect 2 people thru 2 prop voice cards but not 1 card and 1 meeting?

    Any suggestions on how to approach the problem would be really appreciated
