408 Request Timeout Couldn't find the user in time. The server could not produce a response within a suitable amount of time, for example, if it could not determine the location of the user in time. The client MAY repeat the request without modifications at any later time. [1]: §21.4.9 409 Conflict User already registered.
JsSIP uses the SIP over WebSocket transport for sending and receiving SIP requests and responses, and thus, it requires a SIP proxy/server with WebSocket support. Currently the following SIP servers have been tested and are using JsSIP as the basis for their WebRTC Gateway functionality:
In this case, the request should be repeated with another URI; however, future requests should still use the original URI. In contrast to how 302 was historically implemented, the request method is not allowed to be changed when reissuing the original request. For example, a POST request should be repeated using another POST request.
SIP employs design elements similar to the HTTP request and response transaction model. [12] Each transaction consists of a client request that invokes a particular method or function on the server and at least one response. SIP reuses most of the header fields, encoding rules and status codes of HTTP, providing a readable text-based format.
Below is a sample session description from RFC 4566. This session is originated by the user "jdoe", at IPv4 address 10.47.16.5. Its name is "SDP Seminar" and extended session information ("A Seminar on the session description protocol") is included along with a link for additional information and an email address to contact the responsible ...
SIMPLE applies SIP to the problems of: registering for presence information and receiving notifications when such events occur, for example when a user logs in or comes back from lunch; sending short messages, analogous to SMS or two-way paging; managing a session of real-time messages between two or more participants.
408 Request Timeout: The HTCPCP server is unable to make tea for a timeout and forbidden actions. 418 I'm a teapot: The HTCPCP server is a teapot; the resulting entity body "may be short and stout" (a reference to the song "I'm a Little Teapot"). Demonstrations of this behaviour exist. [1] [10] 503 Service Unavailable
Specific examples include: In the Microsoft Windows and ReactOS [2] command-line interfaces, the timeout command pauses the command processor for the specified number of seconds. [3] [4] In POP connections, the server will usually close a client connection after a certain period of inactivity (the timeout period). This ensures that connections ...
