What does a voice gateway do?

A voice gateway is a device that connects a Voice over IP (VoIP) network to a traditional Public Switched Telephone Network (PSTN). It does this by converting analog voice signals into digital data packets that can be transmitted over the internet, and vice versa.

Voice gateways are used for a variety of purposes, including:

• Connecting VoIP networks to the PSTN: This allows users of VoIP phones to make and receive calls to and from traditional landline phones.
• Providing backup call support: Voice gateways can be used to provide backup call processing in case the primary call processing system fails or connectivity with it is lost.
• Connecting VoIP networks to other VoIP networks: Voice gateways can be used to connect VoIP networks from different providers, allowing users to make and receive calls between them.
• Providing additional features: Voice gateways can also provide additional features, such as voicemail, call recording, and conferencing.

Voice gateways are an essential part of many VoIP networks, and they play a vital role in enabling businesses and individuals to communicate effectively.
