I have been interested in VOIP services for awhile, but I never made the leap to buying one of their setups. It seems like they just wanted to sell a boxed setup and charge some fee every month. I have been more interested in a way to get phone calls on my computer and then be able to take it with me wherever I go.
I found a solution in Skype. I signed up for their Skype Pro and got free voicemail and the signed up for a Skpye In number. While it’s not perfect, it does work well for me. I have a portable phone number that I have wherever there is an internet connection.
