 Answering machines on a pots line are able to detect a
 caller hangup based on a loop current drop on the line.

 If that happens before the beep the machine can reset &
 ignore the msg, if the hangup is after the beep, depending
 on the machine it may or may not be able to.

 If your callers are calling via  VoIP / digital  phones
 record will probably detect the hangup pretty fast,
 slower older devices - your mileage will vary.

 Sometimes I use  "press 1 to leave a msg" to reduce the
 number of dead air msgs from callers.
