we have three local/long distance T1s that we use for in-and-outbound traffic. We had a fourth long distance only T1 that was for outbound only. We have since replaced this old, long distance only T1 with a fourth local/long distance T1. My question is, my original 3 in-and-outbound T1s are in one route. Does it make any difference whether I make this new (fourth) circuit a separate route and have this be my second choice for outbound(and make my copper my third choice) or should I program this fourth T1 into the same route that the other three are already in? If we pay the same rates on all four circuits does it matter either way? we have no problem traffic-wise with inbound calls. Thank you.
