Who this is for: Any staff member using a Yealink T54W registered with Barti VoIP.
Before you start, you'll need:
A Yealink T54W registered with Barti VoIP (see How do I configure a Yealink T54W for Barti VoIP?)
The extension number of each phone you want to assign (set by your admin in Barti — see How do I add a VoIP phone in Barti?)
Option A — Set up speed dial from the physical phone
Long-press any side button for 5 seconds until the configuration screen appears.
Use the arrow keys to find and set Type to SpeedDial.
Leave Account ID set to Auto.
Enter a Label for the destination phone (e.g., "Front Desk", "Exam Room 1", "Back Office").
Enter the phone's extension number in the Value field.
Save the entry.
Repeat for each phone you want to assign to a side button.
Video Overview
Option B — Set up speed dial from the web admin console
Log into the phone's web interface by entering its IP address in your browser. (Press OK on the phone to find the IP address.)
Navigate to Dsskey → Line Key.
Find the line key you want to configure and set the following fields:
Type: Speed Dial
Value: Extension number of the destination phone
Label: Name of the destination phone (e.g., "Front Desk")
Line: Auto
Click Confirm to save.
Repeat for each phone you want to assign to a line key.
What you'll see when it works
The label you assigned (e.g., "Front Desk") appears on the side button of the phone. During an active call, press that button to transfer the call directly to that extension without dialing manually.
Troubleshooting
The speed dial button isn't transferring to the right phone.
Confirm the Value you entered matches the extension number assigned to that phone in Barti (Organization Settings → Communications). If the numbers don't match, repeat the steps above to correct the value.
I don't have any side buttons available.
Each side button can only hold one assignment. If all buttons are in use, you can reassign an existing button using the steps above, or use the directory contacts method instead — see How do I transfer a call between VoIP phones in Barti?.
