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
modem?

Thanks
Antonio

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.

Is there any other cheaper option for digium cards?

Have you even bother to take a look at the hardware page at
www.asterisks.org ?

Please read that page!

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