Hello experts!

I currently have a system build on top asterisk to which I would like to add a billing feature.

A2billing of course came to mind. But I'm having some trouble understanding how to integrate my current dialplan with a2billing.

What I have currently is similar to:

[2_2]
exten => s,1,Set(options=)
exten => s,n,Set(result=Answered)
exten => s,n,Set(_dialer_phone=${dialer_phone})
exten => s,n,AMD()
exten => s,n,GotoIf($[${AMDSTATUS}=MACHINE]?machine:begin)
;skipping the machine part
exten => s,n(begin),Set(stage=0)
exten => s,n,Background(message1)
exten => s,n,Swift(${firstname})
exten => s,n,Swift(${lastname})
exten => s,n,Background(message2)
exten => s,n,WaitExten(10)
exten => s,n,Goto(2_2,1,1)

exten => 1,1,Set(options=${options}1)
exten => 1,n,Set(result=Connected)
exten => 1,n,Dial(SIP/${to_dial}@flowroute,,mG(2_2^ans^1));this is actually more complicated, but I didn't want to flood here with irrelevant code

exten => h,1,Gotoif($["${agent}"="true"]?hangup)
exten => h,n,Agi("myagi.jar",<a lot of parameters>)
exten => h,n(hangup),Hangup()

exten => ans,1,Goto(customer)
exten => ans,n,Goto(agent)
exten => ans,n(agent),Set(agent=true)
exten => ans,n,ConfBridge(${dialer_phone},,dialer_user,)
exten => ans,n,Hangup()
exten => ans,n,StopMusicOnHold()
exten => ans,n,Set(agent=false)
exten => ans,n,Agi("myagi2.jar",<a lot of parameters>)
exten => ans,n,ConfBridge(${dialer_phone},,dialer_user,)
exten => ans,n,Hangup()

This works, any error there is just from me cutting parts of it to fit here nicely.

Now, when I was setting up a2billing I thought I would call some script at the beginning of my dial plan and again at the end, and on some other relevant event like the Dial I make. This doesn't seem to be the case. A2billing does everything internally (to my understanding) and I can't see how to implement my dial plan with a2billing.

My question is, can this be done? How can it be done?
