Regarding Caller*ID numbers from PBXs and companies in general, I
remember an article in {Business Communications Review} saying that
ANI (Automatic Number Identification) consists of CNI (Calling Number
Identification) or BNI (Billing Number Identification).

Caller-ID is normally going to give BNI permitting you to block all
numbers from a company location. I don't know what it will do with a
Centrex service where I'd like to know the CNI so I can get back
directly to a caller.

Since ANI was setup for telco billling purposes, I wonder if they use
both BNI and CNI or just one of them for their own billing. Does
anyone know?
