On a 100mb network, orange and green pairs are for data. Blue and brown are unused. So yes you can split the pairs up for phone/data. It's just a real PITA. So you have to split the line at both ends. Not the ideal situation. Note that per spec's on data you should not leave more than 1/2 inch of the wire exposed(without insulation).
Modem and router can be in your office. Feeding the network panel from the office.
Maybe go wireless phones, ha,ha!
