INVITE Sample Clauses
INVITE. Supported: 100rel, timer, precondition Session-Expires: 180; refreshor=uac
INVITE. Support for INVITE is mandatory for both UACs and UASs. The INVITE request is used in many ways: to start a new call, refresh session-timer, reroute (redirect) calls. An INVITE request should have the appropriate headers and may include a SDP body. In case the corresponding INVITE has an SDP body, the ACK should not have an SDP body. The SDP body is necessary for providing early audio. Headers convey specific information about the call such as calling, called party, and the call’s unique identification. Subsequent re-INVITE requests are used to refresh session time, or to change RTP receiving address port and codec. The INVITE request initiates or renegotiates a session may include a SDP body. If originating SIP server does not know its desired characteristic of session until it receives the 200 OK response, the initial INVITE should have not SDP body. In this case the ACK request for this INVITE will contain a SDP body. The INVITE requesting the session-timer refresh requires SDP body. If the INVITE doesn’t contain any SDP, the following ACK shall contain a SDP. It is mandatory for a UAS to support receiving INVITE requests with no SDP body.

INVITE. The figure below shows two applications Foo and Bar being invoked for the terminating party via the SB/SCIM. Both of the application servers (acting as either proxies or B2BUA’s) propagate the SIP INVITE back to the SB/SCIM.
