[asterisk-users] Agent Pre Acknowledgement Message

[Diarmaid O'Loughlin]

I'm trying to wean my self using the Agent channel in Asterisk. The main 
reason I use it is for the callback acknowledgement , where the user 
presses # to finally acknowledge the call. I have implemented this in the 
Dialplan using the Macro in the docs. This works well as long as the user 
enters something. 

However if the user hangs up , then both sides of the bridge call are hung 
up as well , i.e. the customer calling waiting in the Queue, is hungup on. 


I believe the problem is because the Read section of the dial plan will 
return a -1 when the operator being called hangs up on it. 

Has anyone else spotted this ? Anyone Solved the problem ? 

[macro-screen] 
exten=>s,1,Wait(.25) 
exten=>s,2,Read(ACCEPT|screen-callee-options|1) 
exten=>s,3,Gotoif($[${ACCEPT} = 1] ?50) 
exten=>s,4,Gotoif($[${ACCEPT} = 2] ?30) 
exten=>s,5,Gotoif($[${ACCEPT} = 3] ?40) 
exten=>s,6,Gotoif($[${ACCEPT} = 4] ?30:30) 
exten=>s,30,Set(MACRO_RESULT=CONTINUE) 
exten=>s,40,Read(TEXTEN|custom/screen-exten|) 
exten=>s,41,Gotoif($[${LEN(${TEXTEN})} = 3]?42:45) 
exten=>s,42,Set(MACRO_RESULT=GOTO:from-internal^${TEXTEN}^1) 
exten=>s,45,Gotoif($[${TEXTEN} = 0] ?46:4) 
exten=>s,46,Set(MACRO_RESULT=CONTINUE) 
exten=>s,50,Playback(after-the-tone) 
exten=>s,51,Playback(connected) 
exten=>s,52,Playback(beep) 

Here is the console log for the even,
