 The ring-u Hello Hub requires DHCP to properly live on your network. It has a backup static address of 192.168.99.9,​ without a router, DNS and a gateway out, it's only used for emergencies,​ and in the almost 3 years of ring-u, that's only been a couple of times. In other words, it can't be used for the phone system.  The ring-u Hello Hub requires DHCP to properly live on your network.

-Every other customer has had a DHCP server that assigns addresses to various devices. Modern DHCP servers are an excellent way to reserve an address for consistent addressing (and we recommend it at https://​wiki.ring-u.com/​wiki/​doku.php?​id=reliability ). As the Hello Hub is, like many devices, a Linux based system, technically there are ways to assign an address by editing a text file on the system, the next system update would overwrite those configs. Essentially:​ the configs for the many outweigh the configs of the few.  Other "​smart"​ devices like Chromecasts,​ Alexa'​s,​ Doorbells, Thermostats etc.. expect a DHCP server as well. Sometimes there are ways to circumvent that, but the added threat/​attack surface of such an interface is a problem for us.+Every other customer has had a DHCP server that assigns addresses to various devices.

 I'm an old network guy, I like on-device manual IP addressing for some things, but I'm afraid this is not going to be one of those cases. You will need a DHCP server, with at least one available address for the Hello Hub.  I'm an old network guy, I like on-device manual IP addressing for some things, but I'm afraid this is not going to be one of those cases.
