+=====Reliability and Stability=====
 A single page with everything we know about the reliability and stability of Hello Hubs and associated phone service.Ring-u's very first customer (#99) has been online since June 2017. We have thousands of systems out in the field that never have a problem. We've also had a few nightmares and learned a lot.\\
 Things we have learned, in order of applicability:
-===== Reserve an IP Address =====
+====Reserve an IP Address====
 === Our #1 recommendation for system reliability===
-When a Hello Hub boots, it checks to see if it has the same network address it had before, and if not, scansfor phones on your network to tell them it's new address. Your system is much more stable if the Hello Hub always gets the same address from your router/firewall/DHCP server. Most modern small network routers make it easy to find the list of things on your network and reserve an address for the Hello Hub. It will usually show up as "ring-u" in the list of DHCP leases in your router with a one button/click "reserve/assign an address" button. This is often the biggest improvement that can be made in the stability of your phone system.

+====No Port Forwarding====
 Your Hello Hub does not need your firewall/router to forward traffic to it for normal usage. If you do not need external phones, do not forward ports. If you have ports forwarded, your Hello Hub will be constantly probed by the internet by the curious and nefarious. It has an adaptive firewall that blocks probes, but intense/nefarious probing can cause your firewall to shut down access to and from your Hello Hub, and/or cause your Hello Hub to stop communicating.\\
 If this is the suspected cause:
