# NFON Limitations

> Why NFON cannot currently be integrated with Famulor

<Warning>
  **Done for you — any region, any country (our EU partner carrier)**

  If you prefer not to configure a SIP trunk or import numbers yourself, our **EU partner carrier** can supply **local numbers in any region and any country**, set up the **SIP trunk**, and **import the connection into Famulor** for you. Provisioning runs **end-to-end through the partner** (carrier-side), so you skip DIY trunk and number import in Famulor.

  * **Custom number region / full-service onboarding:** [Famulor Custom Number Region form](https://tally.so/r/w4bN2Y)
  * **More detail or bespoke options:** [support@famulor.de](mailto:support@famulor.de)
