- ;transmit_silence = yes		; Transmit silence while a channel is in a
- 				; waiting state, a recording only state, or
- 				; when DTMF is being generated.  Note that the
- 				; silence internally is generated in raw signed
- 				; linear format. This means that it must be
- 				; transcoded into the native format of the
- 				; channel before it can be sent to the device.
- 				; It is for this reason that this is optional,
- 				; as it may result in requiring a temporary
- 				; codec translation path for a channel that may
- 				; not otherwise require one.
