Which protocol does Avaya Gateways facilitate conversion for?

Avaya Gateways play a crucial role in the integration of various communication protocols, specifically enabling the conversion between different types of signaling and media transport used in voice communications. The correct answer, which focuses on PSTN (Public Switched Telephone Network) and SIP (Session Initiation Protocol), highlights the gateways' functionality in managing the interface between traditional telephony networks and modern VoIP systems.

PSTN is a circuit-switched network designed primarily for voice communication, while SIP is a protocol widely used for initiating, maintaining, and terminating real-time sessions that include voice, video, and messaging applications over IP networks. The ability of Avaya Gateways to translate communication between these two protocols is essential for seamless interactions in hybrid environments where both traditional telephony and modern IP-based communications coexist.

SIP enables advanced features and functionalities such as presence, instant messaging, and multimedia communication, while PSTN remains critical for established telephony services. By facilitating this conversion, Avaya Gateways ensure that users can connect to various types of networks effectively and maintain communication without disruptions, making them a vital component in the Avaya ecosystem.
