cc_call or cdr for a2billing?

Hi
I have installed Asterisk2Billing in the server where I installed asterisk before. I created iax and sip users. With the number of the card generated, I try a call , but i got this :

[color=brown]serveurCLI> dial 6710558938
– Executing Dial(“OSS/dsp”, “IAX2/”) in new stack

CLI>[/color]

this is a few lines of the extensions.conf file :
[color=green]exten => 11111,1,Dial(IAX2/issam)
exten => 22222,1,Dial(IAX2/aicha)
exten => _X.,1,Dial(IAX2/${CALLERID})[/color] is this line correct to call the number generate in a2billing ?
In the database mya2billing , should I created a table with all carateristics of cdr table ?

thanks to help me!
Aicha
