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

Sat Aug 30 02:52:30 UTC 2008

Thanks for your kind help of patience. There should be some problems in Username/Passwd configuration. And now, I've settled my problem successfully according to your guidance.

Actually, I made a small and fatal mistake. There was something wrong about the Authorization header field in step 3. Now, I just use "Digest username" to replace "username". And the program runs successfully now.

  I'm a green hand of SIP. And I want to learn SIP well. Thanks again for your kind and patient help.

Thank you, steven.
Thanks again for all of you.

  SEU, zhjlu

              You should configure id/password before making register and invite. I am sure that the sip stack will work if you do that as I said.

    Thank you for your comment. 

  And now, I find that step 3 did not do its work just because that UAC failed to send the new INVITE message with authentication. 

  Are there any reasons which can lead to the failure of "eXosip_call_send_initial_invite(invite)" in step 3?

  Thank you again for all of you!!!

in this case once you recive 401, then  u have to create second invite with correct credintal           .O   {color:black;   font-size:149%;}  a:link   {color:#4D4D4D !important;}  a:active   {color:#993333 !important;}  a:visited   {color:#EAEAEA !important;}        <!--.sld   {left:0px !important;   width:6.0in !important;   height:4.5in !important;   font-size:103% !important;}  -->    or call may be lost due to dialouge

    Yeah. Actually, in step 2, UAC successfully received a 401 Unauthorized message and also an EXOSIP_CALL_CLOSED event at the same time.

  What's more, UAS seems to consider step 3 as the same as step 1, and then take the same action.

    Are you sure that correct user name/password is included in invite message in step 3?

    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
