If you're interested in setting things up quickly as far as using VoIP, follow this quick guide.

When setting your FlyNumber directly to VoIP there are 3 fields you'll want to be familiar with.

They are Protocol, Host, and Username/extension.

Protocol

  • The first thing we'll ask for is what Protocol you'll be using (Hint: it's most likely SIP).
  • This is basically the format thats used to move data between communication systems, sort of like the https protocol you see in urls.
  • If unsure, use SIP as most providers use the "Session Initiation Protocol"External Link Icon for transmitting communications.
  • And for those who know what they're doing, you have the option of using the H.323 or IAX2 protocol as well.

Host

  • Next we ask for a Host.
  • When using an external VoIP provider this is the part after the @ in the SIP address.
  • If you're not sure what your SIP address is, contact your provider or search through their documentation.
  • So if your SIP address is [email protected] the "host" would be sip.acme.com.
  • When setting up a FlyNumber (i.e. DID number) for an external PBX (e.g. Asterisk, FreePBX, etc) this would be the IP address or hostname of your server.
  • So if your Asterisk server is publicly available on IP address 12.34.45.7 then thats what you'd enter as the "host".

Username/extension

  • And finally the Username/extension.
  • If you're using an external VoIP provider this would be the part before the @ in the SIP address.
  • So if your SIP address is [email protected] the "Username/extension" would be john.
  • If you're configuring an extension on Asterisk, for example, you might have an extension number like 101 for a particular phone or user. In this case, you'd enter 101 as the "Username/extension".
  • Similarly, in FreePBX, each extension is associated with a specific user or device, and entering this extension ensures that incoming FlyNumber calls are routed to the correct endpoint.

  • In certain situations, you may need to whitelist our IP addresses in your system's ACL (Access Control List), especially when working with systems like Asterisk or FreePBX.

  • Quick Tip: Set "host" to iptel.org and "user/extension" to music to get started quickly and test the FlyNumber out. You'll hear music when you call the number.
