[Asterisk-Dev] qcall CDR problem

[VoIP]

Hi, I am trying to use qcall to do callback service. And put the qcall file
as follows, 
------------------------------------
SIP/2001 at b.com 1001 at a.com SIP/3001 at c.com 0
------------------------------------
Qcall first initiate a call to 2001 at b.com and wait for his answer, when
2001 at b.com answers the call, Qcall connects to 3001 at c.com. So 2001 and 3001
can talk to each other. Here we set the caller id to 1001 at a.com.   

Actually there are 2 legs in this call. One is 2001 at b.com, and the other is
3001 at c.com. I found CDR only recorded call from 1001 at a.com to 3001 at c.com but
no such CDR from 1001 at a.com to 2001 at b.com.
 
If 2001 at b.com and 3001 at c.com are both PSTN numbers, then it should be a big
problem to charge the callback users. 

Although this is a user level questions, I doubt the CDR mechanism should
have problem.
