This document will show you how to register a Yealink handset to a Base Station.
Requirements
- Office Manager access to the PBX Portal
- Mac Address and model of the Yealink Base Station
Adding Additional Lines to the Base Station
- Login to your manager portal
- Once Logged in Navigate to Inventory
- Click on Phone Hardware
- Click on the Edit button next to the Base Station that you would like to add the additional lines to
- Note: This article assumes that you have already added the base to the portal as well as the additional sip phones, if not please use the steps in the following article How to Add a SIP Phone
- Add the additional Lines as per how many handsets will be connected to the base and click on Save and Resync
- If the phone if offline on the portal, this will not work, it will instead need to be provisioned manually
- Once the phone is back online each handset should be registered and be able to make and receive calls.
Troubleshooting: Not all Handsets are Ringing
Issue: We have a base and 5 registered handsets, but when there are incoming calls not all handsets ringing. Only 4 handsets ring.
Take W70B as an example:
- There is an option called Number of Active Handsets, 5 as default. If there are more than 5 registered handsets, you should change it to 10.
- If you are able to login to its WEB GUI, then this can be found under Features -> General Information -> Scroll down to Number of Active Handsets
For W60B/W80B/W90B, default value of active handsets is 4, max is 8. For W70B, default value of active handsets is 5, max is 10.
