Set Ringtones for Incoming Calls
You can choose which ringtone the Cloud Voice App plays when a call comes in. Set one tone for every call, or give different callers their own sound so you can tell a colleague, a customer, or a specific contact apart before you even look at your phone.
How ringtone rules work
Section titled “How ringtone rules work”You manage ringtones inside each Cloud Voice App separately. A tone you pick on your phone stays on that device only and does not carry over to the desktop or web app.
Your administrator can also assign a ringtone at the platform level for certain call flows, such as a ring group, a call queue, or an IVR (Interactive Voice Response, the automated phone menu that answers and routes callers). Those platform-assigned tones reach you when you belong to the ring group or queue, or when your extension is set as an IVR destination.
When more than one rule could apply to the same call, the app plays the tone from the highest-ranked rule below:
- A distinctive ringtone set for a contact or phonebook
- A ringtone assigned by the platform
- A distinctive ringtone set for internal or external calls
- Your default ringtone
Before you begin
Section titled “Before you begin”Update the Cloud Voice App to at least the version for your platform:
- iOS: 5.17.8 or later
- Android: 5.17.9 or later
The hosted platform side of this feature is maintained by IZT, so no action is needed there.
