Hello,
please I need your help because i have spent 60 days but i didn't succed to make a2billing-cid-callback work.
I have installed a2billing 1.4, asterisk 1.4.22, and freepbx 2.5.1.5, i have installed the deamon of callback and it works fine. this my configuration:

config trunk in freepbx:
Peer details

disallow=all
allow=gsm&alaw&ulaw
canreinvite=no
context=tocallback
host=xxx.xxx.xxx
fromdomain=voipshop.fr
insecure=very
secret=xxxxxx
type=peer
username=33xxxxxxxxx
fromuser=33xxxxxxxxx
qualify=yes
echocancel=yes
dtmfmode=rfc2833


User details:

disallow=all
allow=gsm&alaw&ulaw
canreinvite=no
fromuser=33xxxxxxxxx
qualify=yes
secret=xxxxx
type=user
username=33xxxxxxxxx

extensions.conf:

[tocallback]
exten => 33xxxxxxxxx,1,Goto(a2billing-cid-callback,${EXTEN},1)


[a2billing-cid-callback]
exten => _X.,1,Ringing()
exten => _X.,n,Set(CALLERID(num)=0${IF($[${CALLERID(num):0:2}=00]?${CALLERID(num):2}:${CALLERID(num)})})
exten => _X.,n,DeadAGI(a2billing.php|2|cid-callback|) ;last parameter is the callback area code
exten => _X.,n,Hangup


iam from tunisia so the prefix is 00216 but the callerid received in asterisk with the prefix 0216 only i don't know why asterisk don't detect the first 0 but no pb I have added this 0.

in a2billing i have created a provider, trunk, rate card, rate and a customer. the trunk is the same trunk configured in freepbx so this trunk is at the same time used as an access number and an outbound route to callback my mobile phone witch has the number 0021692144766


so when i call from my mobile phone the access number 33xxxxxxxxxx, the call is routed to the tocallback context then is routed to a2billing-cid-callback but asterisk didn't call me back. this is the output of the server:
