By default the IP Office will use internal music on hold by uploading a music file from the IP Office Manager PC. For IP500v2 systems, you can load a file onto the System SD card prior to installing it in the IP Office. The file must be of the following format and must be called holdmusic.wav. 1. Rename the music file holdmusic.wav. 2. Using a card reader, copy the file into the /system/primary folder on the System SD memory card. 3. If the IP Office is or will be configured for additional hold music files (up to 3 additional files), copy those files to the same location. The name of the additional files must match those specified in the IP Office system's configuration.
The format of the Wav file is important as well. In order to be played by the IP Office the file must be recorded with a bitrate of 128kbps and be recorded in a single channel (mono). The sample size must be 16-bit with an 8Khz sample rate.
Post-install the Music on Hold can be added using Embedded File Management. Just switch to Embedded File Management mode and copy the file to the IP Office SD Card and upload holdmusic.wav to the PRIMARY folder on the SD Card. The other method of loading the IP Office hold music is to use the TFTP Server. When the IP Office is rebooted it will always look for a copy of holdmusic.wav on a TFTP server (if present). The IP Office Manager acts as a TFTP Server while running so this is an easy solution that requires no additional software. The file can just be placed in the working directory of the IP Office Manager software. If you need assistance in configuring additional MoH source files (IPO 4.2+) it is in the documentation. I hope this little bit helps people with their questions.
The IP Office supports multiple hold music selections, based on the incoming call route. You can use a WAV file or an analog extension to provide the music. In order to use different WAV files you need to add them to the control unit using embedded file management. You can enter a friendly name for the source. The source number is specified by the system, starting with 2.
Specify a WAV file using WAV:filename.wav. Specify an extension using XTN:222 (replace 222 with the extension number). When using an extension you need to change the extension to show that it is a music on hold source.
Once you have added your sources you can add them to the incoming call route:
