Play out DTMF tones on the receifing side

Up to V2 R2, OpenStage phones supported DTMF as per RFC 4733 for sending DTMF information to the remote party when the user performed some key pad input.

In V3R0 OpenStage supports this also for the receiving direction. The receiver (B-party) is now able to play out tones (i.e. hear the DTMF tones).

This feature aims at the capability to play DTMF digits received (B-party) using RFC 2833 coding (i.e. Rtp events) in the current active audio device (headset, loudspeaker, handset).

DTMF (as RTP events) are now recognized by the receiving phone (B-party), if in the admin menu the parameter Enable DTMF is set to Yes.

A new configuration item is introduced to allow administrators to switch off/on audible DTMF tones under Phone menu: Admin > Speech > Audio settings



A similar item is included in the WBM.
