XymphonyProgramming-ToneDetectionXymphony has the feature of detecting tones such as busy tone, ringing tone, overflow tone coming from the fxo port. FXO line is released when overflow tone from FXO port is detected. Call progress tone frequencies must be defined in the Common properties / Signalling Table of FXO to use this feature.  These two textboxes are for storing the expected frequencies of dial and ringback tones for the DC loop trunks. If the expected tone consists of a single frequency, fill both boxes with some tolerance. For 500Hz, set boxes to 490 and 510, for 450Hz, set boxes to 440 and 460. Integrated auto dialler uses these values to detect call progress tones to complete the call. DC loop trunks (FXO) of Common properties/Monitor speech path parameter set to Tone detection clears call also uses these values to detect the release of the call by the remote party.  |
