I have had a wrong callback behavior from a2billing.

A few days ago, I have installed a stable asterisk system composed by asterisk 1.4, freepbx and a2billing. I have used the callback function that works very well.

Then, I have dowgraded Asterisk to 1.2.33. And, the callback became not working properly. The wrong behavior is: after calling back the caller, and after the authentication with the card number, the system tries to call the caller itself (the number that the system has already called it == the number already in communication). In other words: The system tries to call the number that it is in communication with!.

Can anyone explain and has the solution to this issue.

please help.

Did you adjust A2B's 'asterisk_version' setting to '1_2' after the downgrade?
