For information on tag construction see Section The behavior of a UA on detection of media failure is a matter of local policy. This ensures that outbound proxies that do not add Record-Route header field values will drop out of the path of subsequent requests. In rare circumstances, where the server cannot process the request without the extension, the server MAY send a Extension Required response.

This mechanism is known as registration. For that target, the replacement above is effectively a no-op. If a client is using an outbound proxy, and that proxy actually redirects requests, a potential arises for infinite redirection loops. Unlike a proxy server, it maintains dialog state and must participate in all requests sent on the dialogs it has established. Ranger les posts par: A stateful proxy has a server transaction associated with one or more client transactions by a higher layer proxy processing component see figure 3known as a proxy core.
Thus, the branch parameter provided with the Via header field inserted in step 8 MUST be different for each attempt.

The behavior of a stateful proxy is further defined in Section UAs wishing to support this capability must take into consideration some issues such as choosing monotonically increasing CSeq sequence numbers even across reboots, reconstructing the route set, and accepting out-of-range RTP timestamps and sequence numbers.
The local sequence number MUST be empty. Unless specified otherwise, values expressed as quoted strings are case-sensitive.
Ce filtre permet donc un grand nombre de réglages principalement pour les possesseurs de home cinéma conttactsay 5. Pour être simple ça ressemble à un petit patch qui s’adresse à Messenger Plus!

Since SIP messages and the sessions ecript establish can pass through entirely different networks, SIP cannot, and does not, provide any kind of network resource reservation capabilities.
This typical arrangement is often referred to as the « SIP trapezoid » as shown by the geometric shape of the dotted lines in Figure 1.

dcript For these requests, the scope of the Contact is global. This location service is effectively a database containing mappings between a single URI and a set of one or more alternative locations at which the target of that URI can be found.
