Comfort noise generation
In digital voice transmission, CNG (Comfort Noise Generation) ensures that the
listener hears a slight background noise in the pauses between speech, otherwise
they might think the connection has been lost.
Out-of-band DTMF
With analogue phones, DTMF (Dual-Tone Multi-Frequency, a multi-frequency
dialling system) is used to dial a number or transmit digits during a connection.
There are two kinds of DTMF:
Out-of-band: DTMF digits are transmitted in the voice-frequency band (above
G.711).
In-band: DTMF digits are transmitted through RFC 2833 signalling (e.g.
when retrieving an external voicemail).
