Extensions

An extension is an employee’s number inside the company. A phone or a softphone is connected to it. Extensions are in “Employees” → “Extensions”.

Create an extension

1. 1Click “Add extension”.
2. 2“Extension” — 2 to 8 digits. The panel suggests a free number by itself.
3. 3“Employee name” — colleagues see it in lists and on their phones.
4. 4“SIP password” — click “Generate”, then “Copy”, and keep the password: the phone needs it.
5. 5Click “Save”, then “Apply” in the yellow bar at the top.

Keep a copy of the password before you create the extension. After saving, you cannot view it again — you can only set a new one in the “New SIP password” field.

An extension cannot be created if its number is already taken by another extension, a group, a queue or a menu, matches an emergency number, or starts with the outside line digit.

Extension settings

Open an extension for editing from the list. Its tabs:

• “Employee” — “Department”, “Position”, email and “Mobile” for the directory; “Outbound Caller ID” — the number people see when you call outside; “Hide the number”; “Call rights”; “Call recording”: “By the PBX’s rules”, “Always record” or “Never record”.
• “Phone and SIP” — “Codecs”, “DTMF (tone dialling)”, “SIP transport”, “Devices at once” (1 to 5), “Call waiting”, “Phone behind NAT (a router)”, “Allowed networks”.
• “Forwarding” — what to do with a call.

Department, position, email and mobile are only for the directory and search; they do not affect calls.

Forwarding

“Ring the phone for, seconds” — how long the phone rings before the “If no answer” condition applies. For each condition, choose an action:

Actions: “Do not forward”, “To an extension”, “To a ring group”, “To a queue”, “To an external number” (through the chosen provider) or “Hang up”.

Many extensions at once

• “Range” — create extensions in a row, for example from 201 to 230. In the “Names” field, {n} is replaced with the number.
• “Import CSV” — load extensions from a table. The whole file is checked first: if it has an error, not a single extension is created.
• “Export CSV” — export the extensions to a table.

Up to 1000 extensions at a time. Download the passwords of the new extensions with the “Download extensions and passwords (CSV)” button while the window is open: you cannot view them later.

Extension state

The list shows whether a phone is connected — “Online”, “Offline” or “Talking” — and its address, device and ping. If an extension is “Offline”, see the article Common problems.
