Wow. Thanks for all that info. That is extremely helpful.

My understanding is that we don't have the PAL chip, but I'd probably have to pull the T-1 card and actually take a look to be sure. Is there any other way to ck?

Through our first provider we had number only caller ID, but we changed providers a while back from a company called Eschelon to Cbeyond and I think you may be right about their T-1 start type. They must differ. Where would I see how this is set on our end?
