[SIPForum-discussion] Hi all , expires time issue.

[ZHAO Jian Wei]

I think you are right .But I test this case use my lab, The flow is as follows

 

The subscriber is deregistered. I know there is a reg-min in sip. Why does the server send 423 interval too brief message?

The server should send 401 response and once again UE will send Register message with the expire header 0 , so that the UE should get unregistered.
This is the default behavior  of the server.

Hi, all

 

 

 

                If  a subscriber does not register . He send the register message with the expire=0, what will happens?

 

 

1.       The server will return "423 Interval Too Brief " 

              or

2.       The server will send 401 and the authentication vector to the user , the user will send the vector and expire=0 to the network again? 

 

 

 

 

 

 

 

 

 

 

           thanks
