asterisk users - Nov 2018 - Detect missed call in extensions?

How I do to detect missed calls?

 

After Dial() has been executed, theres 3 ways a call could end up in:

 

1: The callee answers, and a communication is going on. Then one party hangs
up, and thus execution goes to the h extension.

2: The callee newer answers or there was some error, the Dial() fails, and
execution continues on next line in extensions.

3: The caller hangs up before callee have answered, and execution goes to
the h extension.

 

Now to the problem. I want to detect if callee did answer or not (in
separate 1 and 3) so I could determite if a missed call should be logged to
a missedcall.txt log file. (call should be logged in 3 case, but not in 1
case)

2 is easy to detect, as these always are failed (non-answered) calls.

 

Best regards, Sebastian Nielsen
