asterisk users - Apr 2008 - About outdail SIPCALLID

Hi
     I sent this 3 hours ago, seems not go through, so sent again.

     I have an asterisk php-agi application.
     It answer's call , then outdial to another number:

$agi->exec_dial("SIP", 12345 at test.com , "20",
$options);

      How can I get a SIPCALLID for this out-dialed call?

       The SIPCALLID seems the incoming call's SIPCALLID.



Thanks.

Mike
