A straight T1 clear channel line can get expensive depending on the distance, plus that makes it an OPX (off premise exteansion) line. You should use E&M for the tie line between two routers, then some sort of WAN circuit to bring the two together. You can do anything such as FXS to FXO, etc,. but the proper voice way to do it is E&M. You could do PRI (voice pri, not ISDN) to carry the digits to the other PBX, clear channel, VoIP, VoFR (then you bring in a router of some sort to CODEC and encap the voice).
Basically you need a pyhsical pipe to carry the voice between two I work for a voice company right now, so I am getting all the info right from the voice guys. (Also, I can't seem to escape these Cisco Press authors. One of my instructors at my QoS class at Cisco is Wendel Odom.)
