Caller ID in California: the question you need to ask is regarding ANI, Automatic Number Identification. That is available on 800-numbers and can be delivered in realtime if you have enough traffic to justify a T1. And of course you can get it from any carrier you wish. ANI is *not* Caller ID, they work differently, use different signalling systems. -gg
