I wrote a AGI script which is base on PHP. But I can not get some values, like billsec in CDR, when hangup. Does AGI can access the value? If AGI can not, please tell me some other methods to get the aim.

Who can help me?

Thank you.

I think you should use DeadAGI when the channel hung up…  
But I don’t know anything about CDR.  
Hope it helps.

Hi,

you probably using Asterisk 1.2.x, and due to a bug, Asterisk ‘loses’ some values in hangup, including CDR(billsec). There is a patch for this , search on [bugs.digium.com](http://bugs.digium.com). Then use DeadAGI, and now the CDR values are available.

Asterisk 1.4 does not suffer from this, I think.

exten =\> h,1,DeadAGI(/paht/to/script/xxx.agi|${CDR(xxx)}
