I have one local T1 and one LD T1 on two different definity PBXs. My question is how do I tell the long distance calls going out to use the LD T1 instead of the local T1.

It is probably a simple thing to do but I do not know how to make it do this - any advice on what to do? This would save us some money so I would like to put it in place.

Thanks!
