So you have a Yealink T-49G Voice and video device, but how to do you register it to Pexip for video calls? Well that will depend on what software version you are running. I am running 184.108.40.206, which is the latest sas of 11th December 2017.
There has been some changes depending on the software level which stopped registrations working. So below is the latest overview of the registrations for a SIP registration to a Pexip deployment.
Firstly let's configure the Device Alias on Pexip Infinity. This screenshot is from v17 below. Input the desired alias on how the device will be addressed such as email@example.com. Then select which protocol you want to register with and then some credentials for authentication and click Save.
Now over on the Yealink device, login using a browser as it's much easier. You then head to the Account tab and select Register from the left hand menu. Then enter the details of the Device Alias you created on Pexip. See the orange boxes below on what details to enter. In the Register Name, DO NOT ENTER the full URI Alias created in Pexip, as the Yealink device will append the Server host domain into the Register Name.
Happy calling on your Yealink.
