There is a better device if you have a PRI, an Adtran Atlas 550 is 
basically a full phone switch. You can put an entire dialplan on it to do 
router based on DID/DNIS. It will also do channelized T1 to PRI conversion 
each way. Very slick boxes, I'm about to set one up for another asterisk 
user to split 1 PRI to 12 pots lines for an older switch, 1 PRI for 
Asterisk, 1 channelized T1 for a modem bank, and some FXO ports for an 
older Brooktrout card. If anyone wants more info on them let me know.
