The PBX is ours to run, not yours to maintain.

What replaces the box

Everything that used to be configured on the hardware becomes an object you can see and change from a browser. Nothing about the underlying telephony is exposed as a choice you have to make.

• A line is a person or a role. It has a name, an email and an extension.
• A number is inventory. You assign it to a line, a group or a call flow, and reassign it whenever you like.
• A site is an office. It holds the address, the time zone, the business hours and the calling permissions everything else inherits.
• A call flow is what happens when someone dials a number. It is one diagram, not six modules.

No SIP stack question, ever

Open-source PBX software usually asks which SIP driver an extension should use before the extension can exist. That is an implementation detail dressed up as a product decision. We made the choice once, internally, and per-handset quirks are handled by a device profile you never see.

Changes take effect where you made them

If changing a setting requires a phone to re-provision, we queue that automatically and show the device as pending re-provision until it is done. You should not have to remember that two screens are coupled.
