Examples of javax.sip.SipProvider.sendResponse()

javax.sip.SipProvider.sendResponse()
Sends the Response statelessly, that is no transaction record is associated with this action. This method implies that the application is functioning as either a stateless proxy or a stateless UAS.
- Stateless proxy - A stateless proxy simply forwards every response it receives upstream and discards information about the response message once the message has been forwarded. A stateless proxy does not have any notion of a transaction.
- Stateless UAS - A stateless UAS does not maintain transaction state. It replies to requests normally, but discards any state that would ordinarily be retained by a UAS after a response has been sent. If a stateless UAS receives a retransmission of a request, it regenerates the response and resends it, just as if it were replying to the first instance of the request. A UAS cannot be stateless unless the request processing for that method would always result in the same response if the requests are identical. Stateless UAS's do not use a transaction layer; they receive requests directly from the transport layer and send responses directly to the transport layer.
