Caller ID issue

[Bigpomaha]

I'm new to the 3300 and come from the 5000 world so alot is new to me.  We have two main numbers that come out of our system.  It appears that it is setup so that extesions in the 1900 (clinic) range show one caller ID number and all the 1300 (hospital)  range show another number.  We have a few stray numbers 1800's that need to show one hospital and are showing the clinic.  Where in the programming do i change that??  Any help is apppreciated.

If it's just a hand full of numbers then the easiest way to change the caller ID is in the Associated Directory Numbers form.
Click Add, put in the extension that you want to change the caller ID, select CPN Substitution and put in the caller ID you want to show.
