insertDTMF method

void insertDTMF(String tones, [ int duration, int interToneGap ])

The insertDTMF() method on the RTCDTMFSender interface starts sending tones to the remote peer over the RTCPeerConnection.

Sending of the tones is performed asynchronously, with tonechange events sent to the RTCDTMFSender every time a tone starts or ends.

As long as the connection is active, you can send tones at any time. Calling insertDTMF() replaces any already-pending tones from the toneBuffer. You can abort sending queued tones by specifying an empty string ("") as the set of tones to play. Since insertDTMF() replaces the tone buffer, in order to add to the DTMF tones being played, it is necessary to call insertDTMF with a string containing both the remaining tones (stored in the toneBuffer) and the new tones appended together.

Implementation

external void insertDTMF(
  String tones, [
  int duration,
  int interToneGap,
]);
