-
Normal (Dedicated) Numbers
- Rented directly from famulor.de.
- Can be used for both inbound and outbound calls.
- Typically charged as a monthly rental, with the ability to handle multiple parallel calls on a single number.
-
SIP Integration (VOIP/PBX)
- Connect an existing VOIP or PBX number via SIP.
- This setup allows you to keep your existing numbers while benefiting from famulor.de’s AI.
- Works for both inbound and outbound—but requires you to share SIP credentials or trunk details with us to configure.
- To submit a request, contact us through the chat widget in the bottom right corner of the screen inside the app.
-
Caller ID (Outbound Only)
- When you already have a phone number (e.g., your personal or business line) but don’t want to port it or integrate via SIP.
- You verify ownership (via OTP or a short call) so that number can appear on people’s caller ID.
- Inbound calls won’t be answered by the AI if you use Caller ID alone—it only masks the AI’s outbound calls.
