Frequently Asked Questions

Will the contact's phone ring?
No. Voicemail drops deliver straight to the voicemail box without ringing through, so the contact gets the message without an interruption.
What audio formats work?
Standard voicemail-compatible formats like MP3 and WAV. Test the upload by playing it back inside the action before saving.
How long can the recording be?
Keep it short — under 30 seconds is best for completion. Longer recordings risk being skipped before the message lands.
Are voicemail drops billed separately?
Yes. Voicemail drops use telephony usage credits like any other outbound call. Check your plan's usage rates.
