I am tempted, especially with the their $15/month for 500 minutes deal. I am quite tired of paying my local baby bell approx $35/month even if I never pick up the phone.
My # apparently qualifies for porting.
However, my SIL has it and I've noticed when they call me, all I get in my caller ID display is "Unknown Name" and their #. For whatever reason, their name is not pushed through to those of us on the baby bell service.
Also, can you hook it into your house wiring so your existing phones will work in their current jacks? Same question with my answering machine. Will it still be usable or am I stuck with voicemail with no call-screening capabilities?
