How should I format audio files for custom greetings?
The recommended format for greetings for Talk is G711 M-ULAW or mp3.
Tip: If you uploaded an mp3 audio file for your greeting and the sound quality is being reported differently between an Agent hearing it in the UI and the end-user experience. Try utilizing the G711 M-ULAW format for the greeting.
