Name
Background() — Plays a file while accepting touch-tone (DTMF) digits
Synopsis
Background(filename1
[&filename2
...][,options
[,language
]])
Plays the specified audio file(s) while waiting for the user to
begin entering an extension. Once the user begins to enter an
extension, the playback is terminated. The
filename
should be specified without a file
extension, as Asterisk will automatically find the file format with
the lowest translation cost.
Valid options
include one of the
following:
skip
Causes the playback of the message to be skipped if the channel is not in the “up” state (i.e., hasn’t yet been answered). If
skip
is specified, the application will return immediately should the channel not be off-hook.noanswer
Does not answer the channel before playing the specified file. Without this option, the channel will automatically be answered before the sound is played. Not all channels support playing messages before being answered.
The language
argument may be used to
specify a language to use for playing the prompt, if it differs from
the current language of the channel.
Returns -1
if the channel was
hung up, or if the given filename does not exist; otherwise, returns
0
