In the Cloud Telefonanlage, you can assign more than one device to an extension, creating a call group. But the use of a call group can differ. Here are two examples:

Shared use of an extension

A call group can, for example, be a service hotline where several colleagues answer all calls together. For this to work, it is important that incoming calls are still signaled even if one or more calls are already in progress.

Multiple terminals of one person

The situation is different if an extension is used exclusively by one person who, for example, uses a softphone in the home office and the VoIP to go app on the road in addition to their desk phone in the office.

If this person makes a call on one of the devices, no further incoming calls should be delivered – the connection should be "busy on busy", callers hear the busy signal.

Note on DND and Busy on Busy

The busy-on-busy function distinguishes whether a call is actually being made or only one terminal has been set to DND ("Do not disturb").

If, for example, the DND button is activated on one telephone, incoming calls are still signaled on all other terminals – until a connection is actually established.

Setup steps

1. Call up Cloud Telefonanlage

Open the Cloud Telefonanlage via the easybell customer portal. You will then see an overview of the extensions and devices.

2. Edit extension

You can set the "Busy on Busy" function individually for each extension / call group.

To do this, please click on the icon with the gear wheel next to the extension.

3. Set Busy on Busy

The settings can be found in the "Incoming calls" section.

Check or uncheck "Busy on Busy" and then click "Save" at the very bottom of the page.

If active users are to be able to control this function independently without gaining access to sensitive data or other extensions, we recommend setting up an OfficeDesk.
