RequestPending Class |
The RequestPending class represents Request Pending response with status code 491 and default description text "Request Pending".
The Request Pending response is used to resolve accidental simultaneous re-INVITEs by both parties in a dialog.
Since both INVITEs seek to change the state of the session, they cannot be processed at the same time. While the client
is awaiting a final response to a re-INVITE, any re-INVITE request received must be replied to with this response code.

the client's host name or network address, and possibly the port number at which it wishes to receive
responses. The Via header field value can also contain parameters such as "maddr", "ttl", "received" and "branch".
