Description
Confirms that the client has received a final response to an INVITE request.
Terminates a call. Can be sent by either the caller or the called party.
Cancels any pending searches but does not terminate any call currently in progress.
Allows session-related control information generated during a session to be carried along
the SIP signaling path.
Indicates that a user or service is being invited to participate in a call session.
Immediately upon successful accepting or refreshing of a subscription, a NOTIFY message
is sent to communicate the current resource state to the subscriber. This NOTIFY message
is sent in the same dialog as that created by the SUBSCRIBE message.
Queries the capabilities of servers.
Provides reliability for 1xx type messages; see
Provides a mechanism allowing the party sending the REFER message to be notified of the
outcome of the referenced request.
Registers the address listed in the To header field with a SIP server.
Requests current state and state updates from a remote node.
Allows a client to update parameters of a session, but has no impact on the state of a dialog.
This request can be sent before the initial INVITE has been completed, thereby making it
useful for updating session parameters within early dialogs.
