技术咨询关于收到响应时401的处理时机

[a24211317]

我在SIPProcessorObserver发现processResponse中的一段代码对于401的响应没有做出处理，请问是在哪个地方对401回复处理的。现在遇到了信令回复的401Unauthorized 但是在keepalive的定时中发现响应的是200ok导致上级离线了也没有重新注册
// Success
if (((status >= Response.OK) && (status < Response.MULTIPLE_CHOICES)) || status == Response.UNAUTHORIZED) {
if (status != Response.UNAUTHORIZED && responseEvent.getResponse() != null && !sipSubscribe.isEmpty() ) {
CallIdHeader callIdHeader = response.getCallIdHeader();
if (callIdHeader != null) {
SipEvent sipEvent = sipSubscribe.getSubscribe(callIdHeader.getCallId());
if (sipEvent != null) {
if (sipEvent.getOkEvent() != null) {
SipSubscribe.EventResult eventResult = new SipSubscribe.EventResult<>(responseEvent);
sipEvent.getOkEvent().response(eventResult);
}
sipSubscribe.removeSubscribe(callIdHeader.getCallId());
}
}
}
ISIPResponseProcessor sipRequestProcessor = responseProcessorMap.get(response.getCSeqHeader().getMethod());
if (sipRequestProcessor != null) {
sipRequestProcessor.process(responseEvent);
}
