Choose from 4 powerful ways to use your FlyNumber
1.) Use FlyNumber SIP to make and receive calls
- Make and receive calls with your Czech Republic 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 Czech Republic FlyNumber as the caller ID.
- Register up to 5 devices, with voicemail built in.
- Pick your own Czech Republic number when ordering — search by digits or letters.
2.) Forward the Czech Republic phone calls to any standard phone number worldwide
- For a low per min rate you can forward the Czech Republic calls to any regular phone number in the world.
- You'll see the caller ID of the person calling your Czech Republic 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.
3.) Set the Czech Republic number directly to VoIP
- Set the Czech Republic number directly to a SIP/VoIP address.
- We'll send the Czech Republic 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.
4.) Use our (optional) cloud phone system
- An optional add-on: a full-featured cloud phone system for a flat $14.95 per month, covering your whole account.
- Add routing logic to your Czech Republic FlyNumber — voice menus (IVR), ring groups, business hours, call recording, and up to 30 users.
- Quickly and easily configure the call flow on a digital grid type canvas.
- Outgoing calls from the phone system use the same per-minute rates from your prepaid balance.
- Usually you don't need it — one person with a softphone is better served by FlyNumber SIP.
Note
Switch between them any time from your FlyNumber panel. A fifth setting, Park the Number, stops the number ringing anywhere (callers hear busy) with no call charges.
