5.1 Phone extensions

Overview

Phone extensions are targets. They are the most important of all the target types that are supported by the 1&1 Versatel telephone system and only one of two targets that can make calls to external destinations.

Under Extensions > Phones, you can see a list of all phone extensions that have been configured for the tenant.

In this view, you can:

  • Add a new entry

  • Select one, several or all entries and delete them

  • Edit, clone, delete or edit an entry or copy it to a clipboard (you can also edit an entry by double-clicking on it)

  • Import a CSV file

  • Export a CSV file

  • Select how many entries you want to have on the page

  • Search for a phone extension

Important

Before deleting a target, make sure to check if any other target is referencing it, for example, an eFax, IVR or a skill service, as it will change the configuration of the latter.
