Easy Setup Providers (legacy)
Years ago, FlyNumber kept the SIP host pre-saved for a handful of popular VoIP providers so you only had to type your username — JohnSmith for sip2sip, for example, and we'd append sip2sip.info on our side. This shortcut is no longer in the panel.
The forwarding itself hasn't changed. Under the hood it was always just a SIP forwarding setup with the host filled in for you. You can still send your FlyNumber's calls to any of these providers; you enter the host yourself now using Set to VoIP.
Regardless of which forwarding path you pick — easy setup, Set to VoIP, FlyNumber SIP, or the phone system — toll-free and "Metered" FlyNumbers carry a per-minute incoming rate. Regular numbers stay free on the inbound leg over VoIP. See toll-free incoming rates for the current breakdown.
Connecting to the old "easy setup" providers
The original list of one-click providers included names like:
- CallCentric
- sip2sip.info
- Pbxes
- 12Voip
- VoipBuster, VoipStunt, VoipDiscount, Nonoh, VoipRaider, VoipCheap — all run by Betamax
To connect a FlyNumber to any of them, follow the Set to VoIP flow. You'll fill in two things from your provider:
- Host — your provider's SIP server hostname (e.g.,
sip2sip.info,callcentric.com) - Username — usually the same name you sign in with at the provider
For most hosted services, leave Port blank so the panel's automatic server discovery picks the right server. See the field reference for details.
Search "<your provider> SIP settings" or look it up on your account page at the provider. Hosted SIP services publish their server info — you need it any time you register a softphone to them.
Mobile app caveat for Betamax providers
VoipBuster, VoipStunt, VoipDiscount, Nonoh, VoipRaider, and VoipCheap are all operated by Betamax. Their own mobile apps sometimes drop or reject calls forwarded in from external DIDs like FlyNumbers. If you hit that, register a third-party SIP client (Zoiper, Acrobits Groundwire, Linphone, MicroSIP) against the provider's SIP service directly — that path works regardless of where the call originated.
