Any session can be modified while the session is in progress. The media can be added, deleted, or changed, as can participants. A good example of this would be a Webinar, where participants come and go and the media changes from audio to video and file sharing. When either UA wishes to modify a session in progress, it initiates a new INVITE using the same CALL-ID. The dialog ID is also the same which means the TAG values used

to calculate the dialog ID are not modified from the initial request. The new INVITE contains the modifications and is referred to as a re-invite. The re-invite will also contain all of the session description from the initial request. In other words, the entire session description including the modifications is sent to prevent confusion. This also allows stateful proxies to maintain an accurate status of the session. The SDP will contain the actual changes, so the UAS receiving the re-invite will check the version header of the SDP (v=) to see if a change is being indicated, and will then look to see what was changed from the original request. The UA that initiated the modifications then becomes the UAC for that portion of the session. Remember that only the UAC function can generate a request, but devices support both functions and can interchange roles while sessions are in progress. There is one limitation for re-invites: They cannot be forked by forking proxies. The request-URI contains the address of the UA that the original session was established with, preventing forking of the re-invite. If the receiving UAS chooses not to accept the modifications, then it can respond with 488 NOT ACCEPTABLE HERE without disrupting the initial session. The response only affects the modifications to the session. The WARNING header then provides an explanation as to why the modification is being rejected. If the UAS should send a 200 OK but never receive an ACK, then it will respond with the BYE method. This will disrupt the entire session and result in tearing the session down. It is assumed that the dialog has been lost between the other entities and the UAS must therefore release itself and its resources from the session. Since alerts (such as ringtones) are not typically needed for session modifications, the re-invite will not contain the ALERT-INFO header. Likewise, there is no need for the provisional response 180 RINGING (although 100 TRYING may still be used). This does not mean that user interaction is not supported, however. For example, if video is being added to a call, the user will need to be notified by the application on his or her device that video is being added so that the user can select the video option. The application is responsible for notifying the user with whatever mechanism is appropriate. If no user interaction is required, the UPDATE method can be used to modify a session. When using the UPDATE method, simple modifications can be supported without using the re-invite mechanism.

Any UA can terminate a session. First, remember that a session is the result of a request receiving a positive response (1xx or 2xx). The completion of the handshake and the creation of a dialog must take place first. If there was any other response to the request, the session is then effectively terminated (actually, it never initiated). The BYE method is used to terminate sessions. As seen in previous Figure 5.3, the BYE is sent in either direction, followed by the response 200 OK. This completes the process. The BYE method also terminates the dialog between the two devices.
