9.22 Music On Hold (MOH)
Each system can provide music on hold (MOH) from either internally stored files or from externally connected audio
inputs.Up to 4 different hold music sources are supported.
Legal Requirements
You must ensure that any MOH source you use complies with copyright, performing rights and other local and national
legal requirements.
System Source
The first source is called the System Source. This source is numbered source 1. The possible options for this source are
Tone (see Default Tone below), External (use the input to the AUDIO port on the system) or WAV File (a file called
holdmusic.wav downloaded by the system). For Release 6.x and higher, the system source can be changed without
requiring a reboot of the system.
Alternate Sources
The names of up to 3 alternate sources can be specified on the System | Telephony | Tones & Music tab. Each can be
the name of a wav file. Alternatively they can be the base extension number of an analog extension port. These alternate
sources are numbered sources 2, 3 and 4.
· The wav files are specified as WAV: followed by the file name. For example WAV:music2.wav for the file
music2.wav. Once an alternate wav file source is specified, in situations where the system would download
holdmusic.wav it will also attempt to download the alternate wav file.
· An analog extension port is specified as XTN: followed by the base extension number. For example XTN:224 for
base extension 224. The analog extension must be one that has had its Equipment Classification (Extension |
Analog ) set to MOH Source.
WAV Files
The system can use internal music on hold files that it stores in its non permanent memory. The file properties should be:
PCM, 8kHz 16-bit, mono, maximum length 90 seconds . If the file downloaded is the incorrect format, it will be discarded
from memory after the download.
The files, when specified by the system source or an alternate source setting, are loaded as follows:
· Following a reboot, the system will try using TFTP to download the file or files.
· The initial source for TFTP download is the system's configured TFTP Server IP Address (System | System | LAN
Settings ). The default for this is a broadcast to the local subnet for any TFTP server.
· By default Branch Gateway Manager acts as a TFTP server while it is running. If Branch Gateway Manager is used as
the TFTP server, then the wav file or files should be placed in the Manager applications working directory .
· The name of the system music .wav file should be holdmusic.wav. The name of alternate source .wav files should
be as specified in the Alternate Sources table (System | Telephony | Tones and Music ) minus the WAV:
prefix.
· File storage on Linux based systems
· On Linux based systems, if no successful TFTP download occurs, the system will automatically look for the files in
opt/ipoffice/tones/mohwavdir.
· Memory Card Use
· If no successful TFTP download occurs, the system will automatically look for the file on the control unit's memory
card (in the system/primary folder) and will download it from there if found. On Linux based systems, if no
successful TFTP download occurs, the system will automatically look for the file on the server's disk in the opt/
ipoffice/system/primary folder and will download it from there if found.
· If a music on hold file is downloaded, the system will automatically write a copy of that file to its memory card if
present. This will overwrite any existing file of the same name already stored on the card.
· For files downloaded from a System SD card, the system will download the file again if the SD card is shutdown
and restarted or if files are copied to the card or uploaded using File Manager.
· If a music on hold file is downloaded via TFTP, the system will automatically write a copy of that file to its disk.
This will overwrite any existing file of the same name already stored on the disk.
· The system will download the file again if new files are copied to the disk or uploaded using File Manager .
