1) Start using AEL (remove this context from extensions.conf and add
to extensions.ael):

context a2billing {
  _X. => {
    if("${EXTEN}"="111") {
      Playback(AR_GetGiveToID);
      Wait(2);
      Record(/tmp/asterisk-recording:ulaw,,5);
      Wait(2);
      Playback(/tmp/asterisk-recording);
      Wait(2);
      Hangup();
    } else if("${EXTEN}"="112") {
      Playback(AR_GetGiveToID);
      Wait(2);
      Record(/tmp/asterisk-recording:ulaw,,5);
      Wait(2);
      Playback(/tmp/asterisk-recording);
      Wait(2);
      Hangup();
    } else {
      DeadAGI(a2billing.php);
      Wait(2)
      Hangup();
    }
}

2) Start using extension masks (also works with AEL):

[a2billing]
exten => _111,1,Noop(Dialled 111)
exten => _111,n,Playback(AR_GetGiveToID)
exten => _111,n,Wait(2)
exten => _111,n,Record(/tmp/asterisk-recording:ulaw,,5)
exten => _111,n,Wait(2)
exten => _111,n,Playback(/tmp/asterisk-recording)
exten => _111,n,Wait(2)
exten => _111,n,Hangup

exten => _112,1,Noop(Dialed 112)
exten => _112,n,Playback(AR_GetGiveToID)
exten => _112,n,Wait(2)
exten => _112,n,Record(/tmp/asterisk-recording:ulaw,,5)
exten => _112,n,Wait(2)
exten => _112,n,Playback(/tmp/asterisk-recording)
exten => _112,n,Wait(2)
exten => _112,n,Hangup

exten => _X.,1,Noop(Didn't dial 111 or 112)
exten => _X.,n,DeadAGI,a2billing.php
exten => _X.,n,Wait,2
exten => _X.,n,Hangup
