Kahevo Hākuʻi is now in production.
What a branch gets
A small box, a network cable and a one-time code. After that the branch's phones behave exactly like the ones at the main office: same extensions, same voicemail, same menus, and a call is transferred between sites the way it is between two desks.
Setup by link, at the branch
A branch phone is set up with the same kind of link as any other, pointed at the box. The box fetches the phone's settings from the main office through the encrypted link, so the extension's password crosses the internet only inside it.
Encrypted inside the branch too
The link across the internet was always encrypted. Now a phone set for encryption is also encrypted on the branch's own network, all the way to the box: its signaling and its audio. "Encrypted" means the same thing at a branch as at the main office.
One page to watch them
A Sites page at the main office lists every branch: connected or not, since when, how many phones, the delay on the link and how many packets it is losing. The page follows the branches live.
From there an administrator can:
- add a site and make its enrollment code,
- approve a new box after comparing fingerprints,
- set a limit on calls at once for a thin connection,
- give the site its own time zone for its phones' clocks,
- switch a site off, or replace its box.
If the internet blocks it
Some networks let very little out. If the usual path is blocked, the box falls back to a second kind of connection that nearly every network allows, and switches back by itself when it can.
When the link is full
If a branch's connection cannot carry another call, the next one is turned away cleanly, and the caller is handled as though that phone were unavailable. Better one call to voicemail than six calls nobody can understand.
