Being that the building isn't complete yet, that is still up in the air. We currently have POTS lines (6 of them), and since I don't think we'll need many lines (most likely won't go above 12), we'll probably stick to that. However, in the long run, it all depends on cost. We are already getting a full T-1 dedicated for data. I don't think we'd be justified getting another T-1 for phone lines. And, splitting the current one isn't an option.

Of course, I'm no telecomm expert, so feel free to trample all over my words.
