Method Detail

noAckReceived

void noAckReceived(SipErrorEvent ee)

Invoked by the servlet container to notify an application that no ACK was received for an INVITE transaction for which a final response has been sent upstream.

This method is invoked for UAS applications only and not for applications that proxied the INVITE.

Parameters:

ee - the event that identifies the request

noPrackReceived

void noPrackReceived(SipErrorEvent ee)

Invoked by the servlet container for applications acting as a UAS when no PRACK was received for a previously sent reliable provisional response. It is then up to the application to generate the 5xx response reccommended by RFC 3262 for the INVITE transaction. The original INVITE request as well as the unacknowledged reliable response is available from the SipErrorEvent argument.

Parameters:

ee - the event that identifies the original request and the reliable provisional response

noNotifyReceived

void noNotifyReceived(SipErrorEvent ee)

Invoked by the servlet container for applications acting as subscriber (UAC) when no NOTIFY was received for a previously sent SUBSCRIBE request as specified in RFC 6665. When Timer N expires without receiving any NOTIFY messages for a SUBSCRIBE message, container will invoke this method.

Parameters:

ee - the event that identifies the original SUBSCRIBE request and the final successful response to the subscribe request.
