Every greeting, hold message, menu prompt and after-hours message on your dialer lives on the Audios tab. You can upload a recording, or type a script and turn it into speech. This guide covers both, and where to use the result.
What you need
- You are the account owner, or a team member allowed to make changes on the Audios tab.
- For text-to-speech: money in your wallet, unless your plan includes free characters.
Step 1: Open the Audios tab
- Open your server from My Servers and click the Audios tab.
Each file shows its Filename, Format, Size, Length, when it was Uploaded, and Valid: "good" means the dialer can play it. The list refreshes itself every 30 seconds.

Step 2: Upload a recording
- Click Upload new audio.
- Next to File, choose a WAV, MP3 or GSM file of up to 10 MB.
- Under Save as, type a name you will recognise, such as main-greeting.wav. Use letters, numbers, _ and - only, ending in .wav, .mp3 or .gsm.
- If that name is taken, an Overwrite existing file with this name box appears. Tick it only if you want to replace the old prompt everywhere it is used.
- Click Upload.
Whatever you upload is converted to the phone format the dialer plays and saved as a .wav file.

Step 3: Turn text into speech
- Click Generate with TTS.
- Pick a Voice. Click the play button next to it to hear a free sample.
- Type your script in Text, exactly as it should be spoken. The counter shows how much room is left (up to 2,000 characters).
- Check the Cost and Wallet balance tiles. If your plan includes free characters, the cost says so.
- Click Preview. This creates the audio and charges your wallet.
- Listen. If you are happy, click Save audio, type a name (.wav is added for you) and click Save audio again. The prompt joins your list like an upload.

Step 4: Listen, rename or delete
- Click play on a row to open the player. Download saves a copy to your computer.
- Rename changes the file name. Anything that used the old name stops playing it until you pick it again.
- Delete (account owner only) asks you to type the exact filename. Any queue, menu or schedule still using it stops playing that prompt.
Step 5: Use the prompt
A prompt does nothing until something uses it:
- Call menus: Inbounds tab, Call Menus pill, open the menu. On Basic Details, pick the Greeting prompt, Timeout prompt and Invalid prompt.
- Queues (in-groups): Inbounds tab, In-groups pill, open the queue. On Caller hears, pick the Welcome message, or turn on Repeat a prompt while they wait and pick the Prompt.
- After hours: on the Schedules tab, pick an after-hours audio in a call time or holiday. See Calling hours, shifts and holidays.
- During a call: agents can play clips from a soundboard.

If something goes wrong
Frequently asked
- The dialer can’t play that file. Upload it again through the Audios tab, or generate it again with text-to-speech.
- Pick a file and check the Save as name. If the name is already taken, tick Overwrite existing file with this name or choose another name.
- Previews last about an hour. Generate the audio again (this is charged again) and save it straight away.
- Click Add funds to wallet in the dialog and top up, then try again. See "How wallet billing works".
- Menus and queues use the file name. Open the menu or queue and pick the new name.
