1) Cost of phone service: Went from a normal $70 telephone bill to under $30.
2) Features: Call Waiting, Three Way Calling, Call Forwarding with Find Me, Follow Me, Enhanced Voicemail with Email Notification, Call Someone Now, Website Review of all calls all included!
3) Plug and Play setup! Plugged right into my Linksys Router, and worked from the start!
4) Take my Telephone Service anywhere in the world (that has a high speed connection of course). This is pretty cool, as I can take my VoIP adapter with me on trips and receive calls from friends and family without them having any long distance charges.
Great Product that saves me money.
