I just did some more digging into this as well. The main reason I asked this question is because i noticed a phone jack on the 2wire gateway. I know that with most satellite tv receivers, you can plug your phone line into the receiver, and it will display the caller ID (which indeed is supplied by your phone company). The 2wire gateways are used by a lot of different providers, so I was hoping that maybe there would be a chance that it would read the CID from any phone line, no matter who the provider is.
I went to 2wire's webpage and did a bit of reading and found that these phone jacks are meant as a phone "output" only, i.e. you can provide voip services through the 2wire gateway. So it looks like people who do not use MTS for phone service are SOL when it comes to call display. I am assuming that MTS will be passing their CID info to the Motorola box completely digitally.
