I’ve used Vonage for six years now, and love it.
I keep a basic land line for the alarm system, fax and emergencies, and have that and the Vonage line plugged into a 2-line cordless phone base station. When I travel (in the US) I just forward the Vonage number directly to my cell phone.
I tried a Magic Jack while spending a month in Costa Rica a few months ago and while it worked fairly well, it was a bit of a pain to have to have my laptop on (and the software running) in order to use it... that’s a negative in my mind.
My computer is ALWAYS on at my house and I was paying $40.00 a month for phone service from cable company. I paid $40 for the magic jack and got rid of the cable phone.
Saving for next year $440.
Regular phone service was impossible as my phone lines stayed messed up for last 2 YEARS I had what could laughingly be called service. Ditched the phone company so I could get phone service that worked 4 years ago. It works but the cable bill keeps growing (had internet/cable/phone package). I don’t have ANY premium channels and bill had moveed past $150. Dropping the phone dropped $40 a month.
Waiting for the next bill to see what else will get cut next.
