Hi,
I have Callback working, however, when I send the initial ring, the ringing is not automatically turned off, it goes on ringing. So when the callback comes back, it finds the call engaged.

How can I make it just ring three times and hang up the call. This is my extensions.conf

[a2billing-all-callback]
exten => _X.,1,Ringing
exten => _X.,2,Wait(1)
exten => _X.,3,AGI(a2billing.php|1|all-callback|44)
exten => _X.,4,Hangup
