Even if you find a way of doing this, it won't do what you want because 
IP address assignments can only influence inbound traffic - you would 
also need to make the outbound traffic go via the correct route.

If each ISP has their own T1/E1 to the AS5300, you could possibly put 
each one in it's own VRF - I have no idea if the AS5300 suppots VRFs 
however. Another alternative is to tunnel the calls over L2TP to 
seperate routers for each ISP... again, no idea if the AS5300 can do 
that but it's starting to get into the kind of sutuation where you might 
as well just buy another AS5300.
