    To use my Linux based computer as a VOIP<->PSTN gateway i need a
    special modem or a voice modem or could it be any regular modem?

    All my in office branches will use ATAs connected to a hub, the
    gateway will be to connect the ATAs to the regular phone line (PSTN).

    I already have a modem on my pc, will i be able to use it? Why they
    recommend those digium modems? In what they differ from the regular

    An simplified answer is:

    A modem converts data to signals that can be carried by telephone lines.

    A digium card converts "talk" from the telephone line to digital signals.

    So NO you can't usa a modem to convert "talk" to digital signals and
    YES you need a digium card to connect your asterisk to the PSTN network.

    I did. However,
    works a lot better for learning about Asterisk.
