A gateway VoIP (Voice over Internet Protocol) is a device or software that connects a traditional phone system to a VoIP network. It allows users to make and receive phone calls over the internet, taking advantage of the cost savings and flexibility that VoIP offers.
Gateway VoIPs are essential for businesses that want to take advantage of VoIP technology without replacing their existing phone system. They can also be used by individuals who want to use VoIP services with their home phone.
