Fritzbox
Forward Fritzbox calls to Callina (consumer/SOHO setup).
The AVM Fritzbox does not expose a SIP trunk to outside services. The supported pattern is call forwarding (Rufumleitung) from a Fritzbox-attached number to a Callina-provisioned number.
Step 1 — Provision a Callina number
Callina → Settings → Phone Numbers → Provision EU number.
Step 2 — Configure Fritzbox redirect
- Open the Fritzbox UI (
http://fritz.box). - Navigate to Telefonie → Rufbehandlung → Rufumleitung.
- Click Neue Rufumleitung.
- Choose the rule: immer / wenn besetzt / bei keiner Antwort.
- Set the destination to your Callina number (in international format, e.g.
+43...). - Pick the source number that should be redirected.
- Save.
Step 3 — Test
Call the Fritzbox-attached number. Anna picks up.
Troubleshooting
| Symptom | Fix |
|---|---|
| Redirect doesn't fire | Some FritzOS versions require unchecking "Vorzugsverbindung" |
| Caller's CLI is replaced by yours | Enable "Anrufer-Rufnummer mitsenden" in the redirect settings |
