FlyNumber Features
Every FlyNumber is a real phone number in one of 90 countries, and almost everything on this page comes with it.
Make and receive calls from any SIP app, desk phone or PBX with FlyNumber SIP. Forward calls to a regular phone or to your own VoIP setup. Send and receive texts on numbers with SMS. Change any of it from your panel.
We never tie you down to specific software or a device.
Port in your current phone number from the panel. It's free in nearly all countries.
Numbers start at $2.95 a month. See our pricing.
Four ways to use your FlyNumber
Note
Switch between them any time in your panel. A fifth option, Park the Number, stops the number ringing anywhere (callers hear busy) with no call charges.
FlyNumber SIP: make and receive calls with just the number
SIP is the standard that VoIP apps and desk phones use. Set your number's Call Handling to FlyNumber SIP and we give you the credentials (server, username and password). You plug them into the SIP app of your choice, and your FlyNumber rings there.
- Incoming calls are included with your number's monthly rate: unlimited incoming minutes*, with no per-minute charges on incoming calls.
- Outgoing calls are billed per minute from your prepaid balance at our per-minute rates. No setup fee and no monthly fee for FlyNumber SIP itself.
- Encrypted calls: TLS and SRTP on port 5061 (recommended), or plain UDP on port 5060 for older hardware.
- Works with any SIP app or device. Our docs walk you through Zoiper, Linphone, Groundwire, Bria, MicroSIP, desk phones and PBXs: set up FlyNumber SIP.
Genuine VoIP: forward calls to your own VoIP or SIP address
- Send the FlyNumber calls to any VoIP solution: your VoIP provider, PBX, softphone service or AI voice platform.
- Enter its SIP address (the host, plus an optional port and username) under Forward to SIP / VoIP Address in your panel. Set your FlyNumber to VoIP.
- UDP or TLS, any port.
- Unlimited incoming minutes* when calls go to VoIP, with no per-minute charges on incoming calls.
- Check out our blog post on the difference between forwarding a call and setting to VoIP.
- Detailed call logs to easily debug issues.
Forward calls to any regular phone number in the world
- For a low per-minute rate, paid from your prepaid balance, you can send the calls to any mobile or landline in the world.
- Need more than one phone to ring? FlyNumber SIP rings up to 5 devices at once or one after another, and the phone system adds ring groups and time-based routing on top.
- Callers who withhold their number still reach your forwarded phone; it shows your FlyNumber as the caller ID. Details.

Pick your number
When you order, the panel shows a list of available numbers to choose from. Search by digits, or by letters that map to keypad digits (NYC, for example). Hit Refresh for a new batch.
Choosing a number holds it for 10 minutes while you check out.
Pick your own number in the US, Canada, Australia and 50+ other countries. Where a list isn't offered, we assign one for you. The "Pick specific #" filter on the coverage page shows exactly where.

Our cloud phone system (optional add-on)
Usually you don't need it. One person with a softphone is covered by FlyNumber SIP. A team, a voice menu, business hours or call recording is when you add our cloud phone system: $14.95/month flat for your whole account, with no setup fee and no per-user fee, plus the FlyNumbers you connect to it.

Frequently asked questions
Do I need the phone system to make outgoing calls?
No. Set your number's Call Handling to FlyNumber SIP and you can make and receive calls from any SIP app, desk phone or PBX, with your FlyNumber as the caller ID. Incoming calls are included; outgoing calls are billed per minute from your prepaid balance. Some number types restrict outbound calling due to local regulations.
Does voicemail work with every Call Handling option?
Voicemail is built into FlyNumber SIP. Turn on "Take a message when nobody answers" for the number and callers can leave a message after the ring timeout. Numbers set to forward to a phone, forward to a SIP address or park don't get FlyNumber voicemail. The phone system has its own voicemail module.
Can I choose my phone number?
In the US, Canada, Australia and 50+ other countries, yes. When you order, the panel shows a list of available numbers and you can search by digits or letters. Where a list isn't offered, we assign one for you. Use the "Pick specific #" filter on the coverage page to see exactly where you can choose.
Can I send text messages from my FlyNumber?
Yes, from numbers with the SMS out capability. Sending works by default from the SMS inbox in your panel, with per-segment pricing on the rates page. It's meant for personal, person-to-person texting; bulk, marketing or automated (A2P) messaging isn't supported. Texting US numbers isn't available yet — it's coming soon (A2P).
Can I keep my current phone number?
Yes. Submit a port-in request from your panel. Pick the country and number type, upload the signed letter of authorization (LOA) and a recent bill, and we handle the carrier side and keep you posted. Porting in is free everywhere except Switzerland, Hungary (local and national numbers) and Sweden (mobile and toll-free numbers). It typically takes a few business days for US and Canadian numbers and 1–3 weeks internationally.
How many calls can my FlyNumber take at once?
Every number comes with 2 channels, so two calls can be in progress at the same time. Toll-free numbers come with many more. If you need extra channels, contact support and we'll add them for you.
