Audio Files
Upload and manage hold music, greetings, IVR prompts, and announcement recordings.
The Audio Files page is where you upload, organize, and manage all audio assets used throughout your phone system. These files power IVR greetings, queue hold music, voicemail prompts, and call flow announcements.
Overview
The Audio Files page displays all uploaded files with their name, duration, format, size, and where they are currently used. Files can be previewed directly from the list.
Supported Formats
| Format | Extension | Notes |
|---|---|---|
| MP3 | .mp3 | Recommended for most use cases |
| WAV | .wav | Higher quality, larger file size |
For telephony use, audio files should be mono, 8kHz or 16kHz sample rate. Higher sample rates work but are downsampled during playback. Keep files under 10 MB for optimal loading.
Uploading Audio Files
Navigate to PBX and select Audio Files
From the main navigation, click PBX and select Audio Files.
Click Upload
Click the Upload button in the top-right corner.
Select your file
Choose an MP3 or WAV file from your computer. Enter a descriptive name for the file (e.g., "Main IVR Greeting", "Support Queue Hold Music").
Preview and save
Use the built-in player to preview the audio before saving. Click Save to upload the file to VoiceCenter.
Audio File Types
Different parts of the phone system use audio files for different purposes:
IVR Prompts
The voice recordings that greet callers and present menu options. Example: "Thank you for calling Acme Corp. Press 1 for Sales, Press 2 for Support."
Upload these on this page, then assign them when creating IVR Menus.
Hold Music
Music or messages played to callers while they wait in a Queue. You can use a single track or upload multiple files for variety.
Voicemail Greetings
The message callers hear before leaving a voicemail. Can be set per extension or as a system default.
Announcements
Short messages played during a call flow, such as "Your call may be recorded for quality purposes" or "We are currently experiencing high call volume."
After-Hours Messages
Messages played when the office is closed, typically configured through Business Hours routing.
Managing Audio Files
Replacing a File
To update an existing audio file (for example, re-recording a greeting), click the edit icon on the file row, upload the new version, and save. All references to that file (IVR menus, queues, etc.) automatically use the updated version.
Deleting a File
Click the delete icon to remove an audio file.
Before deleting an audio file, check that it is not assigned to any IVR menu, queue, or call flow node. Deleting a file that is still referenced will cause those components to play silence or a system default tone.
Recording Tips
- Record in a quiet room with no echo or background noise
- Speak clearly at a consistent pace and volume
- Keep greetings under 30 seconds and hold messages under 2 minutes per loop
- Use a professional tone that matches your brand
- Test recordings by calling in and listening as a caller would
Consider recording in the same voice for all prompts to maintain a consistent caller experience. If using professional voice talent, batch-record all prompts in one session.
