I bought one last time off of woot as well.
Service is ok,
Forgot to cancle the prime service and was charged the monthly fee, in addtion to the taxes, which brought it close to what my land line costs before. Had to call them to downgrade to basic service.
Needed to move my cable modem and router to a spare bedroom to tie the ooma system back into my phone wiring. Since it is there, we don't use the ooma voice mail and just use our answering machine as we use to.
Phone quality is ok. Generally use our cell phones anyway, so in our situation, the house phone is more of a backup, or and addtional phone for babysitters, and family to call on occasion. Mostly telemarketer call and hang up.
The dial tone is a little annoying, but not that big of a deal.
Few issues getting setup, had to have ooma setup the dialing to get the 1 to auto dial for some reason, I thought I tried to setup on my end, but that didn't seem to work correctly for me. It could have been my error, I just don't remember.
The caller block on the prime service was a nice feature, but it seemed like I was always adding numbers to it. The telemarketer seem to have a lot of diffent numbers from the same caller, so not sure it would be worth the hassle of checking them each day. they never leave messages so you don't really know who the numbers were from. I tried some reverse lookups, but had mixed results on trying to figure out who they were.
All in all, ok swich for our circumstances.
