T1 will give you positive hangup and remote end answer information. At
10 lines, you should be close to the break even point between analog and
T1 delivery. Also later upgrades in service like adding lines is just a
matter of turning up the new pairs and reconfiguring asterisk. No new
wiring. If you go the PRI route, it is possible to piggyback data on the
unused lines until you need them for phone calls.
