The dialed number can be provided via dialed number identification service (DNIS) or direct inward dialing (DID). Blueworx Voice Response can receive and use dialed number information if the information is transmitted by the switch as DTMF or MFR1 tones in the voiceband or as dial pulses on the signaling channel. Dialed number information might not be available, depending on the switch to which Blueworx Voice Response is connected, and how the trunk interface is configured.
