Setting call progress tone parameters for outbound dialing

Call progress tones are primarily used for outbound dialing and call transfer. Tracking the tones allows Blueworx Voice Response to return the status of a call to the state table that attempted to make or transfer it. The state table can then take suitable action in response. For example, if a busy tone is detected, the state table can terminate the call and try again later.

Note: This section applies only to Channel associated signaling (CAS).

Blueworx Voice Response can detect the following types of tone:

Blueworx Voice Response cannot detect dual sequential tones (sequential tones that, in turn, consist of dual tones).

To support tone detection, parameters must be configured correctly to match those sent by the national telephone network or by the local PBX.

After you have used Pack Configuration to define your telephony environment, the system can recognize standard call progress tones that are sent by your national telephone network. You can use the Pack Configuration window to view the call progress tone settings. If you need to change these, for example, to configure the system to recognize tones sent by a specific PBX, ask your Blueworx representative to use System Configuration to reset the values. To do this, the Blueworx representative needs a list of the nominal values and valid ranges for tones provided by the switch.
