A question for you BH guys:

How do you guys identify a phone number from your customers house/bus. without using that number to call a phone with caller id? For example, with Verizon there is a number that when dialed will quote to you the number you are calling from.

And how many different phone numbers can BH provide for one customer?

I'm just curious, I'm a Verizon tech and sometimes someone will ask me questions like that and I'm like hell, I don't know lol.
