Creating extensions

An extension is an internal telephone line. Each user can have assigned one or more extensions in Kerio Operator.

The total number of extensions is limited to three times the number of licensed users.

Adding new extensions

You have three options to add a new extension:

• An extension is created automatically when you connect a provisioned phone to the network.
• You can create an extension in Configuration > Users — the extension is assigned to a particular user.
• Create an extension in Configuration > Extensions — the extension is created as standalone (without being assigned to a user).

Creating a standalone extension

If you have a phone which is not used by any particular user, you can create a standalone extension for it.

1. In the administration interface, go to Configuration > Extensions.
2. Click Add > Add Extension.
