Danny Cohen first demonstrated a form of packet voice in 1973 as part of a flight simulator application, which operated across the early ARPANET.[69][70]
VoIP calling as your home phone service is the best way to consolidate calling and networking in one convenient place, while saving a lot of money. Landlines are limited, and serve no more function than dialing out and receiving calls. Setting up your VoIP phone to forward calls to your mobile number is just one of the many ways you can stay connected, even when you’re not home. A common concern in making the transition to VoIP is that giving up your landline service will ultimately mean giving up your number in exchange for a new one. With number portability, residential VoIP providers allow you to keep your old landline number and assimilate it into your new phone service. Check with your VoIP provider to see if your particular number is eligible for porting, as they are portable in most cases.

E911 (Enhanced 911) is a little different to traditional 911 services and is something that you should be aware of. With E911 you need to provide your home address, and this information gets passed to the emergency services if you dial 911. The concerns are that if you have a power outage or an Internet outage then you will not be able to dial 911. If you have a cell phone then you can dial 911 from your device. If you are ONLY reliant on VoIP for your phone service you should be aware of this situation.
