Tone Reception

Collecting Digits and Analyzing Call Progress

The CSP provides tone reception for collecting digits and for analyzing call progress. The software maintains separate tone receiver pools for DTMF, MFR1, MFR2 (Backward and Forward), and call progress reception, dynamically configured and verified upon start-up. These pools are shared resources, for all channels to use.
