In this tutorial we will configure a Yealink handset, to a SIP device assigned to a user inside PBX. 

Yealink devices are used as an example, as they are the most widely used handset on our network. However, PBX supports any softphone or handset that support the SIP protocol.

Additionally, the Yealink devices are extremely reliable and tested internally by our engineering team with PBX, this is another reason why we heavily recommend these units. 

Should you not be using Yealink handsets, apply techniques shown in the article to configure your manufacturer of IP handset. Or alternatively contact our support department for assistance.  

Follow the instructions, supplied in the device user manual to assemble the handset. The diagram below will also supply a visual representation of where the cables will need to be plugged in, using a Yealink device. 

Connect the internet port to an Ethernet cable plugged into your internal network, the power supply and the PC port to an Ethernet port attached to your computer, if required. 


Once plugged in find your phone’s IP address, press the OK button on the Yealink device. Locate the address listed in the IPv4 section. 

Type the IPv4 address into your web browser to access the web-interface. Making sure that your PC is on the same network range as your handset. 

Locate the login details of you handset and enter them into the login page, if the handset has been purchased via us then the details would have been emailed during the order process. 

Click on the accounts tab inside the Yealink portal. 

Login to your PBX customer portal, click on the SIP devices tab and locate the device you want to configure. 


Next, fill in the details in the Yealink web portal from your SIP device information you have as below.

Check all the fields carefully, confirm that they match the details in your SIP devices section of PBX and make sure that you have applied the configuration inside PBX before trying to register a new device. 

Change the line active field from disabled to enabled, and click confirm. The registered status should appear if the details have been entered correctly. 


Locate settings tab then time and date. Ensure DHCP time is disabled, click on the timezone drop down menu and select the relevant time zone. 

Click on the settings tab and then SIP, change the local SIP port to a digit above 6000 making sure that each device has a different local SIP port.
