Firmware Not Updated

Ensure that the firmware for the Yealink device is updated to the latest firmware. For further information on how to update the firmware on your Yealink device, please see our article on How to Update Firmware for Yealink Phones. 

Phone Provisioned Incorrectly

Ensure that the Yealink device was provisioned correctly in the Phone System and Managed Provisioning Portal as indicated in our Provisioning Yealink Devices article. 

Incorrect Outbound Proxy Server Port

A common issue when provisioning is that the port of the outbound proxy server is incorrect due to the port of the proxy server not being configured correctly in the provisioning menu. The main symptom of this issue is that the phone will be provisioned, but calls won't be able to be made. 

1. Find the phone's IP address and enter that into a web browser.
   • If you're unsure how to find this, visit Yealink's support portal to find your phones manual which will have instructions on how to find this in the menus.
2. Go to the Account tab.
3. Scroll down to the SIP Server 2 section.
4. Ensure that for the Outbound Proxy server 1 field, the port is set to 5056.

Incorrect Outbound Proxy Server Parameters

Another common issue is the Server Host or the Outbound Proxy Server not being accurately defined. To help to avoid these problems, please ensure that you have the following parameters set in the phone: 

1. Go to the Account tab.
2. Check that the registered name and user match the extension created on the phone system. 
3. Make sure the password matches with the password that was given by the phone system, which should have been provided in your welcome email. 
4. The Outbound Proxy Server setting should be set to Enabled. 
5. The Outbound Proxy Server should be set to proxy3.bvoip.net.
   • Your proxy server may differ depending on your server's datacenter location, compare against a working phone or reach out to bvoip Support to ensure the right server is used.
6. The Outbound Proxy Port should be set to 5056.
7. Transport needs to beset to DNS-NAPTR.
8. NAT needs to be set to Disabled.

BLF Keys Not Working

The Yealink MP phone series does not support DSS key as BLF in hybrid mode. If you are wishing to have a phone that supports BLF keys, then it is recommended to use a Yealink non-Teams based phone.

Otherwise, if you're using a non-MP based device and your BLF keys aren't working, please reach out to bvoip Support with the extension and phone model, and we'll review the templates in question.
