Figure 1 Busy tone detection
You can configure busy tone detection by customizing busy tone parameters or configuring automatic
busy tone detection. If the tone that the router receives from the PBX matches the busy tone parameters,
the router considers the tone as a busy tone and shuts down the FXO interface.
Configuring a busy tone standard
Two busy tone standards are available: European standard and North American standard. After you
specify a standard, the device uses a set of parameters compliant with that standard for busy tone
detection. If the actual busy tone data do not completely match the set of parameters, the device can use
customized busy tone parameters or automatic busy tone detection to accurately detect busy tones.
To configure a busy tone standard:
