Side-by-side comparison of the old order screen and the new FlyNumber detail page. The new detail page shows a single number's call handling, number information, billing, and SIP accounts.

"Time flies" (no pun intended) would be an understatement here. The first thing we need to do is give a big thank you to all our long-term users — those who stuck with us through thick and thin, who were understanding when we had bugs and patient as we rolled out core features. I (as the founder) can't convey enough the appreciation I have for you. While some may look at the relationship as simply transactional, I do not. We've helped you communicate with friends, family, and customers/clients (for the business owners) throughout the years, and we appreciate your trust in that respect. We're excited to start the next chapter — the OGs here will always have a special place in our hearts.

In the last decade-plus we've shipped plenty of updates, but if we're honest, most of them were patches stacked on top of patches — new features bolted onto a panel that was first built back when "the cloud" still sounded like a buzzword. Today is different. This is the single biggest update we've ever released, and it touches just about everything: how you choose a number, how you make and take calls, how you text, and how you see what you're actually paying for.

Back in 2022, I wrote a piece about entrepreneurs not taking full advantage of SIP (Session Initiation Protocol), and looking back, I feel like I was onto something...

The potential was there: an open, reliable technology that could save businesses money and give them more control over their communications. Looking back now in 2025, that post feels prescient - but with a twist I hadn't anticipated.

Introduction: The Hidden World of SIP Security

I was browsing around on Hacker News and if you're not familiar, the good stuff is usually in the comments. I was intrigued by this comment (by @kkielhofner) and how he/she illustrates a common but often overlooked misconception about SIP. Specifically, the misunderstanding pertains to the role and implications of port 5060 and its associated traffic in a standard SIP deployment.

**Now anytime anyone calls your FlyNumber you can answer the calls for free with unlimited incoming minutes on your iPhone or Android, when you make an outgoing call you’ll pay ourlow per minute rate and have your FlyNumber show up as the Caller-ID. **

This has been the most anticipated feature coming out of our PBX/ Virtual Phone System; it will enable you to register a SIP device/client with our own internal SIP addresses. No need to use a 3rd party VOIP provider, just choose a phone number and send the calls to our “PBX”. You’ll have the ability to register multiple devices and use our legendary PBX Grid to configure your configuration. It’s never been easier to make and receive phone calls with your FlyNumber.

It’s been a while since we’ve updated the blog, our apologies . We’ve been very busy updating the “internals”, we’re about to introduce FlyNumber SIP addresses among other neat features. The exterior may look the same but there’s plenty going on inside. We’re coming out with new features almost every quarter and the PBX/ Virtual phone system is evolving very nicely. You need to try it out if you haven’t already, it’s visually appealing and the grid gives you a real sense of customization.
