Which protocol does Genesys Cloud use for signaling sessions in call management?

Genesys Cloud employs the Session Initiation Protocol (SIP) for signaling sessions in call management. SIP is a widely adopted protocol for initiating, maintaining, and terminating real-time communication sessions that encompass voice, video, and messaging applications.

SIP's flexibility and efficiency make it ideal for managing multimedia sessions over IP networks. It is specifically designed to handle the signaling aspect of call management, allowing for easy setup and teardown of calls, as well as enabling features like call forwarding, caller ID, and conferencing.

In contrast, other listed protocols serve different purposes. Ethernet is a protocol used for networking at the data link layer but does not focus on call signaling. SS7 is a set of telephony signaling protocols but is primarily associated with traditional telephony systems rather than IP-based communications. H.323 is an older protocol that was once used for voice and video communications but has largely been superseded by SIP in modern implementations, including those used by Genesys Cloud. Therefore, SIP's relevance and functionality in the context of call management make it the correct choice for this question.
