[asterisk-users] dialstatus and cancelled calls

[Ex Vito]

  ...as long as the destination does not answer you'll get
  a NO ANSWER disposition.

  Note, however, that "answering" can be one of:

  - Dial a phone and the user answers the phone
  - Connecting the caller to voicemail, for example,
    after Dial timed out
  - Playing an IVR / sound / music
  - And more... Anything that connects the caller!

  So, if in your case you want to know if a user answered
  the phone, then, yes, you will have to add the DIALSTATUS
  value to the CDR, probably in the CDR's userfield.
