Voice Prompts

Voice Prompts are used to store recordings for auto attendants. This feature also has the ability to store files used for Music on Hold. After adding the subscription, you can edit the subscription which will allow you to upload files into the Voice Prompt/Music on Hold storage space. When set to only Voice Prompts, then these files will be made available to rule chunks which allow them to be played as part auto attendants. When selected for music on hold, then all the files will be made available to music on hold chunks as well. You will also have the option to choose your default music on hold.

Please note, we cannot play any music which is DRM protected as it will be only playable on the devices you have been authorised to play it on - which does not include our systems.

This is enabled by ticking the Music on Hold checkbox within the subscription. It works the same as prompt space, you can simply add files to the space provided. Clicking on the file will allow you to toggle its status - whether it is on the default Music on Hold playlist.

Details on how to record a new voice prompt can be found here.

File formats

We currently support:

  • WAV
  • MP3

Please note, remove all metadata, album art, lyrics etc.


Multiple language support is available. Default files should be stored in the format of filename.wav format. If you require a different language filename, this should be stored in the format of filename_en.wav - where "en" represents the country code of the language (this could be any string but 2 letter ancronyms are very readable).

To change the file played a user can be played a option like:

When a call comes in for 9 then play ourintro.wav wait for the user to dial 1,2,3.. and go to extensions playfile,changelang respectively.

Our file says something like: 'dial 1 for english or neu 2 ar gyfer Cymraeg' (the second bit is 2 for Welsh).

When 2 is selected the rule jumps to changelang: When a call comes in for changelang then set the country code to wales then jump to extension playfile.

Both routes eventually end up at playfile: When a call comes in for playfile then then play the recording completed.wav then hangup the call with the reason normal clearing.

When you support multiple languages you must ensure you supply files for both the base filename and the language filename. In this example complete.wav and completed_wales.wav.


We have the following storage limits in place

  • Voice prompts: Max file size 5MB, 100 files
  • Voice prompts + Music on Hold: Max file size 20MB, 1000 files

Up to 10 Music on Hold files can be marked as default, each call will pick 1 default file, at random, to play as Music on Hold.


Note, as per our terms and conditions, you are responsible for the content you store for your use within your phone system. This includes ensuring you have the relevant legal rights to play the content to a public audience via our system.

To obtain a license to play music which is coptyrighted can be done through both PPL and PRS. PPL collects and distributes money on behalf of record companies and performers. PRS for Music collects and distributes money on behalf of songwriters, composers and publishers.

The music babblevoice plays by default is not copyright restricted in anyway and has been contributed to the public domain, so no license is required on your part to play this.

If you want to change your music on hold to your own choice but do not wish to pay for a PRS and PPL license then there is a lot of royalty free music available on the Internet, here are some examples
