Was there no Company greeting ?

I normally do a

"Hello, thanks for calling Bob's Big Boy". for the company greeting so it can be readily changed

Then set Custom service 1 for day and record the stuff that doesn't change much like dept to dial or names of extensions etc
Then set Custom service 2 for night messages

Under services open each time mode and select the CO greeting as needed then open incoming call service and set to what custom service you want.

i am presuming you set the integration up under system parameters first as it would default to a TAW, TDE or TDA?
