Message Creation ← Knowledge Base Do I have to type out my message even if I'm uploading a .wav file or recording my own message instead of using the text-to-speech feature? How do I create a message? How long can my message be? What is text-to-speech (TTS)? What is the 'Alternate text message/page message'? Why do I get an error message saying I can't record a message? How does the “Retries” feature works under “Phone Call Delivery Options”?
