Watercolor illustration of a desktop computer, server, smartphone, tablet and laptop, the kinds of devices you can register with FlyNumber SIP.
FlyNumber SIP
Your own SIP credentials from FlyNumber (SIP is the standard that VoIP apps and desk phones use). Register any SIP app, desk phone or PBX, up to 5 devices, and make and receive calls, with voicemail built in. Incoming calls are included with your number's monthly rate; outgoing calls are billed per minute from your prepaid balance. Set up FlyNumber SIP.

Forward to a Phone Number
Send calls to any mobile or landline, anywhere in the world, at a low per-minute rate from your prepaid balance. How forwarding works.

Forward to SIP / VoIP Address
Already use a VoIP provider, PBX, softphone service or AI voice platform? Point your FlyNumber at its SIP address and calls arrive there with no per-minute charges on incoming calls: unlimited incoming minutes*. Set your FlyNumber to VoIP, connect an AI voice platform like VAPI or ElevenLabs, or see how it works with any VoIP solution.

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.

Technical Details

  • When forwarding to a regular phone number, the receiving phone doesn't need internet, VoIP, or data - it works just like a normal phone call!
  • You'll see the caller-ID of the person calling the FlyNumber on your forwarding device.
  • Call out with FlyNumber SIP or the phone system and your FlyNumber is the caller-ID. With the phone system you can also customize the caller-ID, to tell calls from different FlyNumbers apart for example.
  • FlyNumber SIP is encrypted (TLS and SRTP) and rings up to 5 devices per number, all at once or one after another.
  • If you forward to a regular phone number and blocked callers call the FlyNumber, the call may not connect (it's the receiving carrier's policy). You may want to answer with FlyNumber SIP or your own VoIP instead.
  • Read about the difference between forwarding a call and setting calls to VoIP.
  • Detailed call logs, incoming and outgoing with the cost of each call, to easily debug issues.

Forwarding calls when using our cloud phone system

The phone system is an optional add-on: $14.95/month flat for your whole account, with up to 30 users. One person with a softphone is covered by FlyNumber SIP; add the phone system when you need call routing logic. Do I need the phone system?

Destinations can be regular phone numbers, your own VoIP / SIP address, or SIP accounts inside the phone system.

Ring up to 3 destinations at the same time with a Ring Group, or configure a Queue for unlimited destinations with round-robin routing and music on hold.

Mix and match destinations with other modules -call recording, call menus, voicemail, date/time-based routing, etc.

Changes on the phone system grid take effect right away.

Frequently Asked Questions

Do I need internet or data to receive forwarded calls on my phone?

No! When using regular phone number forwarding, the receiving phone doesn't need internet, VoIP, or data - it works just like a normal phone call. Internet is only needed if you answer with FlyNumber SIP, your own VoIP, or the phone system app.

How can I forward calls to multiple team members at once?

With FlyNumber SIP one number can ring up to 5 devices, all at once or one after another, with no phone system needed. For bigger teams, add the phone system: a Ring Group rings up to 3 destinations at the same time, and a Queue handles unlimited destinations with round-robin routing and music on hold.

Can I set different forwarding rules based on business hours?

Yes, with the phone system. Use the Time Router module to create schedule-based routing. For organization-wide schedules, you can also set up Time Schedules to manage availability for all team members.

How do I record calls when forwarding to my phone?

Call recording is a phone system feature. Use the Call Recorder module in your call flow, enable recording in your app settings, or use on-demand recording with feature codes. Recordings can be delivered by email, or to Google Drive, Dropbox, OneDrive or FTP/SFTP.

What happens if nobody answers a forwarded call?

With FlyNumber SIP, turn on voicemail and the caller can leave a message after the ring timeout; you get an email and the message lands in the Voicemails inbox in your panel. With the phone system you can also send unanswered calls to its voicemail module, forward them to another destination, or use a Queue. Every call, answered or not, shows in your call logs.

Can I connect my FlyNumber to an AI voice agent?

Yes! Set your FlyNumber to Forward to SIP / VoIP Address and point it at the SIP address of platforms like VAPI, ElevenLabs, Retell and others. Your AI assistant handles the incoming calls, and because it counts as VoIP there are no per-minute charges on incoming calls: unlimited incoming minutes*.

Can I transfer calls between different forwarding destinations?

Yes, with the phone system you can transfer calls using feature codes. Set up attended transfers to speak with the recipient first, or use unattended transfers for immediate forwarding.

Can I make outgoing calls with my FlyNumber?

Yes. Set your number to FlyNumber SIP or use the phone system and you can call out from any registered app or device, with your FlyNumber as the caller-ID. Outgoing calls are billed per minute from your prepaid balance at the rates on our Rates page; incoming calls stay included. Some number types restrict outbound calling due to local regulations.

Do I get voicemail?

Yes, voicemail is built into FlyNumber SIP, no phone system needed. Turn on "Take a message when nobody answers" for the number, upload or record a greeting, and get each message by email (with an optional .wav attachment) and in the Voicemails inbox in your panel. Numbers set to forward to a phone number or to your own VoIP don't get FlyNumber voicemail; the phone system has its own voicemail module.
