Synopsis
RECORD FILEfilename format escape_digits timeout[offset_samples] [BEEP] [s=silence]
Records the channel audio to the specified file until the
reception of a defined escape (DTMF) digit. The
format argument defines the type of file to
be recorded (wav, gsm, etc.). The
timeout argument is the maximum number of
milliseconds the recording can last, and can be set to -1 for no timeout. The
offset_samples argument is optional; if
provided, it will seek to the offset without exceeding the end of the
file. The silence argument is the number of
seconds of silence allowed before the function returns despite the
lack of DTMF digits or reaching the timeout. The silence value must be
preceded by s= and is also
optional.
Return values:
