Close....... The T-1 is set up as Line Type 1 T1 Type TIE. I can dial from an executone set to the Zultys, via Transparent Intercom dialing, over this tie line and get answered by the Auto Attendant in the Zultys.This works fine.
I can dial from my Zultys phone to an Executone extension over the PRI and talk to anyone on the Executone. This works fine.

The problem i am having is when i attempt to transfer a call from Executone to Zultys. The call follows the Y-C screen, hops on the same T1 channel as when i call it, but the Zultys does not see any digits.
If i transfer a call from one Executone system over T-1 to another Executone System i can see 3 digits being passed in Ctrl-C. Those digits do not seem to be getting to the Zultys.
