The read-only dtmf
property on the
RTCRtpSender
interface returns a
RTCDTMFSender
object which can be used to send DTMF tones
over the RTCPeerConnection
. See Using DTMF for details on how to
make use of the
returned RTCDTMFSender
object.
Syntax
var dtmfSender = RTCRtpSender.dtmf;
Value
An RTCDTMFSender
which can be used to send DTMF over the RTP session, or
null
if the track being carried by the RTP session or the
RTCPeerConnection
as a whole doesn't support DTMF.
Only audio tracks can support DTMF, and typically only one audio track per
RTCPeerConnection
will have an associated RTCDTMFSender
