More money. The 4 port cards are roughly +$200 more.

Of course, you can add as many VoIP phones to your network as you want,
so I would stick with using at most the two port card, TDM20B:

Two analog port gives you an easy transition to VoIP and once the office
is up and running it gives a dedicated fax extension and one you can
easily use for Modem access (out to clients).

Of course... these days you can also get incoming lines from VoIP
providers - at much lower rates than the monthly Bell offering. So you
don't really *need* the POTS line card (as long as the provider can port
your home or office number).
