There are a multitude of VOIP systems out there. It's hard to make a choice. Ooma was launched last year and is a one-time fee VOIP service that actually has a really good looking handset. Plus there is the option of getting more features if you are ready to pay a monthly fee. We think that the basic module will be good for most users. There is also the possibility of low-cost international calls.
The Ooma system that will cost you $250 gives you the following features, including unlimited US calling with no monthly fees. There is caller-ID, call-waiting, voicemail and low-cost international calling rates. You can also elect to keep your current phone number. The Ooma Hub and Scout bundle can support one phone handset. Each extra phone will need to be connected to a Scout. One Hub supports up to 4 Scouts.
The Ooma Premier service will cost you $13 a month or $100 a year. You'll get a virtual phone number, the ability to listen to your voicemail via email, enable it to ring on your mobile simultaneously or forward calls, different personal numbers and private voicemails for different users, and call logs.
This whole setup is pretty elaborate and sophisticated. It's best for power-users and people who use their phones a lot, who are trying to save money. For basic users, we recommend a service like Call Centric, which is cheap and affordable. You could also just use the Skype services. [via Ubergizmo]
