A while back, I got a lot of advice here (mostly good experiences) about changing from Verizon to VOIP...I ended up using Charter, since they are my cable provider and actually use a different "channel" for the phone service...unlike other services which use the same as your internet. So far it has been a nightmare. The phone loses dial tone, I lose internet, come conversations cut off in the middle, etc. Their service has also been terrible. They actually missed appointments 3 days in a row! And they didn't even know it - each time they apparently entered it wrong or lost it! Even the original installer (a contractor of charter) seemed to say that folks who could not put up with a lot of initial bugs and troubleshooting might not be happy with it. Apparently, it sometimes takes a while to get it right. Certainly it may eventually work - but my patience is wearing thin. Saving $30 a month just may not be worth my while in this case. Amazingly enough, we had a MAJOR medical emergency here (a guest) after the new phone line was installed...and luckily the 911 call worked that time...but what if I would have picked up the phone and had no dial tone? It would have taken me a long time to get my cell, and figure out what to do on it. Anyway, that's the story for beginners.
