Music On Hold
If two parties (say 'A' and 'B') have established a call, one of the parties ('B') may try to connect temporarily to a third party ('C'), e.g. for making a consultation call. The other party ('A') is not involved in this new connection, but is put into the "hold" status: Party 'A' is now able to receive audio information (e.g. music or voice) - which is normally done to inform him/her about this "hold" status by playing a so called "Music on Hold (MoH)".
optiPoint IP phones are shipped with a build-in MoH sample, providing MoH at the near end (i.e. the phone that is being held generates the Music on Hold itself.
Providing a customized MoH requires 4 steps:
- Select a source file with the desired voice/speech - pls. note that this is subject to copyright and other legal regulations.
- Install the MoH file generator tool and the SOX tool on a Windows PC.
- Convert the source file: The file format for MoH is proprietary to the optiPoint IP phones and has to be created by running the MoH file generator tool.
- Download the converted file to the phone - as described in the administration manual.
Source file:
The source file has to be in the * 
WAV format (???any details on format, size, duration???)
Transforming the file is done by a little command line tool (MoH file generator) that does three things:
- Performing a command line call to the SOX tool for transforming the audio data
- adding some information elements specific to the optiPoint phones
- merging this data into a result file
