Updating Phone Buttons (Speed Dials & BLF)

Introduction

This short guide helps you customize the keys for your desk phone, things like Speed Dials and Busy Lamp Field (BLF) lights, using the self‑service user portal.

What you can do with this guide:

Add or change Speed Dial buttons for extensions or external numbers

Add BLF keys for user to see coworker status (idle/ringing/on a call) and optionally pick up their ringing calls

Reorder keys and manage sidecar/expansion modules

Time required: About 3–5 minutes per phone once you have the portal link and login. If your company locks button editing, you may see read‑only screens, use the request template at the end and IT can apply the changes for you.

Before you start

What you’ll need:
- Your portal URL (e.g., https://pbx.precision-computer.com)
- Your username and password (Username will generally be your ext@companyname)
- Office Manager Permissions (Contact Support if needed)

What these do:
- Speed Dial: Press to instantly call a number or to transfer a call to that number.
- BLF: A light that shows a coworker’s line status (idle/ringing/on a call) and lets you pick up or speed dial them or transfer calls to them.

Tip: Button names vary slightly by brand (Poly, Yealink, Cisco, Grandstream) and by portal skin. Look for Buttons, Line Keys, Programmable Keys, or Phone Settings.

1. Log in and locate phone

There are 2 main ways you may update a specific device

Option A: Users Tab

Open the portal: Go to https://pbx.precision-computer.com and Sign In.

Go to Users Tab

Click on The name or Pencil Icon to select user to edit

Select Phones tab

Select Gear Icon next to the phone you would like to edit

Cordless phones usually do not have layouts that can be edited and will not show the gear icon

Now it will load into Button Builder where you can edit the phone layout

Option B: Inventory Tab

Open the portal: Go to https://pbx.precision-computer.com and Sign In.

Go to Inventory Tab

Select Phone Hardware tab, in Inventory page.

Select Gear Icon next to the phone you would like to edit

Cordless phones usually do not have layouts that can be edited and will not show the gear icon

Now it will load into Button Builder where you can edit the phone layout

Part B: Add a Speed Dial button

Click on an empty Key slot.

Type or select Speed Dial (sometimes called BLF/Speed Dial or Favorite).

Number/Value/Target: Enter the extension (e.g., 203) or full phone number (e.g., 15555551234).

Label: Type the button name you want to see on the phone (e.g., HR, Chris, Support).

(Optional) Account/Line: If asked, leave as Line 1 unless you use multiple lines.

Click Save (or Apply).

Quick check: If your phone screen shows pages (1/2/3), pick a Page, Row, or Key number if the portal asks for it.

Part C: Add a BLF (Busy Lamp Field) button

Click on an empty Key slot.

Type/Function: choose BLF or User BLF.

Extension/Monitored User/Value: Enter the coworker’s extension (e.g., 203).

Label: (Optional) Enter the coworker’s name (e.g., Chris B), if left blank system will use name assigned to extension.

Click Save (or Apply).

The light will show: Green = idle, Blinking Red = ringing, Solid Red = on a call, Gray/off = no status or error (exact behavior varies by phone brand).

Part D: Reorder or move buttons

Drag and drop by dragging the Key number to place a button in a specific spot.

If you have a sidecar/expansion module, be sure you are editing the correct Module (1, 2, …) and Page.

2. Send changes to the phone

Click Save in the portal first. Or Save and Resync.

Push the update to your phone using any one of these (depends on your portal/phone):
- Save and Resync button, which is visible when clicking arrow next to the Save button.
- Reboot the phone from the portal.
- Manual reboot: Unplug power (or network if PoE), wait 5 seconds, plug back in. Or pressing reboot menu option on the phone itself.

Wait ~1–2 minutes for the phone to pull the new config. The new labels should appear.

Common examples

Speed Dial to external number:
- Type: Speed Dial
- Label: Help Desk
- Number: 16608271500

BLF for coworker at extension 214:
- Type: BLF (or BLF/Speed Dial)
- Label: Alicia
- Extension/Monitored: 214

Troubleshooting

My new button didn’t show up
- Make sure you clicked Save/Apply in the portal.
- Resync/Reboot the phone.
- Confirm you edited the correct device/sidecar.

BLF light doesn’t change
- Verify the extension is correct.
- Confirm the monitored user is in your same domain/tenant.
- Ask IT to check BLF permissions for your user (some systems restrict who can monitor whom).
- Reboot your phone after changes.

I can’t edit buttons
- Your company may lock this feature. Ask IT to temporarily enable self‑service button editing or to make the change for you.

I don’t see the same menu names
- Look for similar terms: Buttons, Line Keys, Key Layout, Programmable Keys, or Phone Settings. The path differs by phone brand and portal theme.

Quick Reference (Cheat Sheet)

Portal path: Devices/Phones → Buttons/Keys

Speed Dial: Label + Number (ext or E.164)

BLF: Label + Extension (enable Pickup if desired)

Push to phone: Save → Resync/Reboot → Wait ~1–2 min

Sidecar: Pick Module + Page before placing keys

Optional: Popular phone brand notes

Poly/Polycom: BLF is Busy Lamp Field; pickup often called Directed Pickup. Keys may be under Line Key vs Soft Key tabs.

Yealink: Look for DSS Keys; BLF is BLF or BLF List; pages 1–3 map to screen pages and sidecars.

Cisco/Grandstream: Similar wording; ensure you’re placing keys on Line Keys (not Soft Keys) for persistent buttons.
