We have volp (voice over internet protocol) and love it for several reasons. 1. no more sales calls 2. our YEARLY cost is about $13.00 yes per year. I think its 1/2 a penny a call. Granted we don't use it that often but if you don't want unwanted calls its the cats ass. NOW the bad: once you sign up you have to go to there site and manually put in every persons (friends,neighbors, work, doctors etc) everyone that you want to talk to in your data base. ONLY those people will be able to contact you, all others will just get a busy signal. Its quick and easy to enter those numbers. Get international calling, long distance calling etc. included. something to research.....
