The steps
- 1Sign in to the RingCentral Admin Portal.
- 2Go to Phone System → Groups → Call Queues and open the queue callers reach on your main line.
- 3Click Greeting & Hold Music, then under Music settings enable “Waiting in queue music” and/or “Hold music” and click Edit under each.
- 4In the Set Audio dropdown choose Custom, upload your file, click Done, then Save.
Format gotcha
The Hold music toggle under a single user's extension only plays for calls that employee personally answers and holds — it does nothing for callers waiting on the main line. For that you must set it on the Call Queue.
