Name

Monitor() — Monitors (records) the audio on the current channel

Synopsis

Monitor([file_format[:urlbase][,fname_base][,options]])

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.
