Busy lamps (BLF) on desk phones

Multi-key SIP phones (Yealink, Grandstream, Fanvil, Snom …) and their expansion modules can show the state of colleagues on their keys: a receptionist typically watches 10–15 people, an operator console many more. AiPBX publishes these states; the keys are set on the phone (by hand today, by the provisioning page later — see the roadmap).

What a key shows

Set the key type to BLF and the value to what it should watch:

Key value Lamp Pressing the key
1001 (an extension) off/green: free · red: on the phone · blinking: ringing calls 1001; while it blinks, picks up the ringing call
DND1001 red while 1001 has do-not-disturb on on 1001’s own phone: switches do-not-disturb on/off
CF1001 red while 1001 forwards all calls on 1001’s own phone: cancels the forwarding (set it with *72 or in My Phone)
QUEUE1001 red while 1001 is logged in to a queue and not on a break on 1001’s own phone: logs in to / out of all its queues

An extension’s state covers all its devices (desk phone, web phone, app). The DND, CF and QUEUE keys of another user can be watched by anyone, but only that user’s own devices can switch them; pressing someone else’s gives two beeps.

Pickup from a blinking key: the phone dials the pickup code and the extension in one go (*21 + 1001 = *211001). Set the phone’s directed pickup code to *21 (or the code set on PBX → Feature codes).

Voicemail lamp: phones of users with a voicemail box show new messages (message-waiting lamp and count); the voicemail key should dial *97.

Setting a key by hand

The SIP account on the phone must be the user’s desk phone account (extension, password and the portal’s address). Then:

Menu names differ slightly between firmware versions.

Checking it

On the server:

asterisk -rx "core show hints"          # 1001, DND1001 … with their state and number of watchers
asterisk -rx "pjsip show subscriptions inbound"

A key that stays dark: check that the phone is registered with its desk phone account (not the web phone account) and that the value is exactly the extension number. Watchers 0 on core show hints means the phone has not subscribed.
