Distribute — Call Classifier

Altitude Call Classifier

Accurately classify unsuccessful calls as voicemail, answering machine, fax, invalid, rejected, and more. Only human-answered calls reach your agents — keeping productivity at its peak.

Accurate Classification for Maximum Productivity

To achieve the highest predictive dialling performance, Altitude Dialer classifies calls that were not connected to agents — also called unsuccessful calls. Call classification is usually provided by the telephony switch; however, switch classification is very limited, typically only classifying calls as busy or no answer.

Altitude Dialer accurately classifies unsuccessful calls as voicemail, busy, no answer, answering machine, fax, invalid, rejected, and more. Calls that are not answered by human contacts are not transferred to an agent, helping to maintain high productivity levels.

  • Accurate classification beyond basic busy/no answer
  • Detects voicemail, answering machine, fax, invalid, and rejected calls
  • Non-human calls are filtered before reaching agents
  • Maintains high agent productivity throughout campaigns
  • Complements predictive dialling for optimal performance
