What is Cisco Voice Gateway?

A Cisco Voice Gateway connects a traditional telephone network to an IP network, enabling voice and fax communication over the internet. It translates between different signaling and media protocols, allowing devices like analog phones, PBXs, and the PSTN to interoperate with a VoIP (Voice over IP) system. It is commonly used for businesses that want to integrate their existing phone systems with modern IP-based communication solutions, supporting features such as call routing, security, and voice quality optimization.
