The routing of the cloud telephone system is extremely flexible because it consists of two components:

  1. The phone number or extension
  2. The device (account)

By flexibly linking these two components, you can quickly and easily adapt the routing of your cloud telephone system to your requirements.

We'll show you how.

1. Open Cloud PBX

2. Edit extensions

3. Basic settings

To specify the basic settings of your extension, a name, the extension type and a call number mode are given.
The extension can be named, defined and assigned a call number mode here.

You are now in the overview of your selected extension / call group and can edit it as usual.

4. Edit devices

Click on edit to assign devices to the extension.
End devices can be assigned to the extension here.

Please scroll down to the "devices" area and click on "Edit" next to "Assign devices".

5. Assign devices

A new window appears in which you can now add existing end devices to the "Assigned end devices" column by clicking on them.

If you want to add more devices, please read "How do I set up devices in my Cloud Telefonanlage?".

Simply right-click to specify the end devices to be assigned to your extension.
By specifying the devices, they are added to the extension.
