**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.
