How does Charter Telephone® use Voice over Internet Protocol (VoIP) technology?
A. Unlike other VoIP providers, calls travel over Charter’s private network, which eliminates the need for you to have an Internet connection. With Charter, your calls never rely on the public Internet, which can affect performance. Because of this, we are able to offer our telephone subscribers a Quality of Service guarantee, whereas other VoIP-reliant providers are able only to provide subscribers with a “best effort” pledge of service.
