About the billsec in CDR record of meetme

Posted:Fri 02 of Apr, 2010 (07:28 UTC)
THis is my extension include:
exten => _XXXXXXXXXX., 1, NOOP(${CDR(clid)})
exten => _XXXXXXXXXX., n, Dial(SIP/${EXTEN},60,tT)
exten => _XXXXXXXXXX., n, hangup

exten => _X., n, Set(CONFNO=${EXTEN})
exten => _X., n, MeetMe(${CONFNO},pdqxwM,${EXTEN})
exten => _X., n, Hangup

Use the AMI to hold a meeting.
First Use the extension "conferenceā€œ to call someone and then use the "meetme" to put it into the chanel used for conference.
Like This:
Action: Originate
Channel: local/2006@conference
Context: MeetMe
Exten: 2006
Priority: 1
callerid: 2006
Timeout: 30000
Async: 1
ActionID: 123

But when finish this ,I find out that the billsec in CDR record is always 0.......
