If the trunk group type is not currently set to ISDN and it is working then it IS NOT an ISDN trunk group. Type "tie" indicates that it is a plain vanilla T1 and changing it to ISDN will simply make it stop working.
You cannot send outbound caller-id on a plain vanilla T1. You will have to issue a change order with your LD provider to get an ISDN circuit provisioned ... either changing the existing circuit (risky) or having a new circuit installed and then cancelling the old one once you know the new one is working properly.
