Monitor() — Monitors (records) the audio on the current channel
Starts monitoring a channel. The channel’s input and
output voice packets are logged to files until the channel hangs up or
monitoring is stopped by the StopMonitor() application.
Monitor() takes the following
arguments:
file_format
Specifies the file format. If not set, defaults to wav.
fname_base
If set, changes the filename used to the one specified.
options
One of two options can be specified:
m
When the recording ends, mix the two leg files in to
one and delete the original leg files. If the variable
${MONITOR_EXEC} is set,
the application referenced in it will be executed instead of
soxmix, and the raw leg files will
not be deleted automatically.
soxmix (or ${MONITOR_EXEC}) is handed three
arguments: the two leg files and the filename for the target
mixed file, which is the same as the leg filenames but
without the in/out designator. If ${MONITOR_EXEC_ARGS} is set, the
contents will be passed on as additional arguments to
${MONITOR_EXEC}. Both
${MONITOR_EXEC} and the
m flag can be set from
the administrator interface.
b
Don’t begin recording unless a call is bridged to another channel.
