Reliability and Stability

Goal: A single page with everything we know about the reliability and stability of Hello Hub's and associated phone service. Ring-u's very first customer (#99) has been online since June 2017. We have hundreds 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:

The Hello Hub has a built in backup battery good for more than 4+ hours without power. That's why you have to reboot it with the off and on switch. It was designed to be plugged into a common outlet or outlet strip with 110-120vac.

  • Some UPS's and power strips turn off or go into “green/eco” mode when they don't sense their primary load, usually a computer. This makes the Hello Hub run on battery for a while, then die.
  • Some UPS's are “spikey” when they cycle on/off, and that spike causes the Hello Hub's protection circuit to trip, which protects the Hello Hub. But it means the Hello Hub (and your phones) are offline.

Best way to reboot or power cycle a Hello Hub:

  1. Turn off via the power switch on the back.
  2. Unplug the power cable.
  3. Make sure the lights are off.
  4. Turn the Hello Hub on (with it unplugged).
  5. You should see lights on the front. This indicates the battery is good.
  6. Plug the power cable in.
  7. In 2-3 minutes you should have a working system.

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.

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. 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:

  1. Reboot your firewall/router and modem.
  2. Wait for your internet access to return, usually takes a couple of minutes.
  3. Reboot your Hello Hub.
