Any device can be used to make and receive calls with your FlyNumber.

Choose from 4 powerful ways to use your FlyNumber
1.) Use FlyNumber SIP to make and receive calls
- Make and receive calls with your Slovakia number in any SIP calling app from the app stores — Zoiper, Groundwire, Linphone and more — or on a desk phone. We help you set it up.
- Incoming calls are included in the number's monthly rate; outgoing calls are billed per minute from your prepaid balance, with your Slovakia FlyNumber as the caller ID.
- Register up to 5 devices, with voicemail built in.
- Pick your own Slovakia number when ordering — search by digits or letters.
2.) Let an AI voice agent answer your Slovakia calls
With Call Handling set to AI voice agent answers, a built-in agent picks up your Slovakia number. It answers questions from what you tell it, takes messages and transfers callers to you.
You set it up in plain language in your panel. A rule is a sentence and an action: "When the caller asks for the owner, transfer them to my mobile."
$0.10 per minute of AI conversation, billed per second. No monthly fee for the agent.
3.) Forward the Slovakia phone calls to any standard phone number worldwide
- For a low per min rate you can forward the Slovakia calls to any regular phone number in the world.
- You'll see the caller ID of the person calling your Slovakia FlyNumber on the phone you're forwarding to.
- Change the forwarding number anytime via the FlyNumber panel.
- Consider our optional cloud phone system to enhance call forwarding options.
4.) Set the Slovakia number directly to VoIP
- Set the Slovakia number directly to a SIP/VoIP address.
- We'll send the Slovakia calls to a VoIP destination for free (unlimited minutes).
- High level call logs to help diagnose/debug any issues.
- Use any 3rd party VoIP provider or your own PBX system (Asterisk, FreePBX, 3CX, etc.)
- In your FlyNumber panel this is the Forward to SIP / VoIP Address option.
Note
Switch between them any time from your FlyNumber panel. Two more settings live there: Park the Number, which stops the number ringing anywhere (callers hear busy) with no call charges, and the optional cloud phone system, $14.95 a month for voice menus, ring groups and business hours.
