Question: 1 / 485

Which SIP request is used to terminate a session?

CANCEL

INVITE

BYE

The request used to terminate a session in the Session Initiation Protocol (SIP) is indeed BYE. When a participant wants to end a session that has been established via SIP, they send a BYE request to the other party involved in the session. This effectively informs the other participant that the sender wishes to terminate the ongoing communication and results in the release of resources associated with that session.

In the context of other SIP request types: CANCEL is used to abort a request that is pending; INVITE is used to initiate a session; and OPTIONS is used to query the capabilities of the server or other participants without actually initiating or terminating a session. Understanding the specific function of each SIP request is crucial for effective communication management in SIP-based systems.
