I could give that a try and see what happens. All of my inbound and outbound calling is working, configured as T1 (E&M Wink Start). If I reconfigure as PRI, I am afraid my call functionality will stop. The local T1 only has 12 channels and the LD T1 has all 24 channels available. I can surely give it a try and see what happens though.

The C/L account reps have repeatedly told me that this customer is on T1 E&M and that to achieve this functionality would require an upgrade to a PRI circuit. They currently do not receive any calling info on the inbound calls on the old PBX, but every outbound call shows their name/number. I would think that if C/L is supplying this, it should show up on every call regardless of the PBX connected to the circuits.
