“Drop Delay Time” doe not have too much impact on the detection result, so you

Detecting busy tone according to step 2:
Observe whether FXO port has detected correct busy tone signal or not. If busy tone
is detected, FXO will be released immediately.
If busy tone is learned successfully, but it can not be detected, you can modify the
parameters and repeat the detection progress; if both learning and detection are
successful, you need save the configurations, and back up the parameters of the busy
tone which was learned just now. However, if for both of learning and detection are failed,
you can record the busy tone by software or some other tools, and send it to our
company. Our technical experts will help you make it.
