How would I configure ISDN Call by Call in eManager to set a single PRI to use an ILG set to CO and an OLG set to TIE?

If I try to just set this in program 302, it gives me an error that "The type of ILG or OLG entered is not ISDN", but from what I've been reading, it sounds like I could use Call-by-Call to do this. Correct?

What are you trying to do? It seems that you are trying to route your outbound calls over a TIE line to a different system and then out from there? Call-by-Call is more for using a single PRI for multiple facilities. If you want your outbound calls to route over a different circuit, use LCR.
