[SIPForum-discussion] Which events can trigger an EXOSIP_CALL_CLOSED event?

[正军 陆]

Hello, everybody:
      I ran into a problem today. And I don't know what actually the problem is. 
   
      I send an INVITE to initialize a call, as the following describes:
      UAC<-------------------------------------------------------------------------------->UAS
      1)-----------------------------an INVITE message------------------------->
      2)<-------------------a 401 Unauthorized message-----------------------
      3)---------a new INVITE message with authentication------------->
      4).....
   
      but, before step 3) does its work, UAS always receive an EXOSIP_CALL_CLOSED event. Where is the problem? Thank you for your kind help.
   
  SEU, zhjlu
