1. depends on how many voice lines, types etc.
basic voice on a small cisco has a 2 port FXS, E+M or FXO daughtcard -
either on the router itself for some models, or for a carrier module that
has DSPs to do voice processing.
there are several country varients for the earlier versions. - so lots of
choices...
(as well as ISDN BRI and various PRI interfaces - be careful you get voice
rather than packet based interface flavours for ISDN).
you can get some idea of the model numbers here:

bigger router slots etc:

2. ask in the comp.dcom.sys.cisco group.

you might find a 1750 / 1760 - but be aware that the DSPs, feature in IOS
and a 2 port analog interface may be worth more than the router.....
26xx / 37xx / 37xx would need a network module and voice cards in that AFAIR
FWIW you are supposed to get a new licence for a 2nd hand cisco for the IOS.
it may well be cheaper to keep the router and get an ATA (analog telephone
adaptor) - the popular ones get mentioned here frequently.
