# Create and Edit Custom Extensions

Use this page to create or edit an extension that routes to a custom dial target or external endpoint behavior. The form works against the tenant currently selected in the top bar.

The screenshots use the **Canistracci Oil** demo extension **106 Gia Parker**. Creating and editing use the same form: a new extension opens with tenant defaults, while an existing extension opens with saved values.
