3CX Windows client not connecting to Yealink phone

[tsherven]

I am new to 3CX. We just installed our environment last week and so far I'm very impressed. There are a few things that I can't get working though. We are running 3CX version 16.0.676 with Yealink T54W phones. I setup my web client and can successfully interact with my Yealink desk phone. I've installed the Windows client, but it won't interact with my Yealink phone. It works fine as a soft phone, I can see all of my extensions, etc. I've switched the Windows client to "Desk phone CTI", but it still behaves as a soft phone (even though it shows up as CTI in the client).

Any ideas of why it works with the web client but not the Windows client?

Thanks!

The most common issue I can think of would be related to the network, often there are data/voice VLAN's in place blocking the connection between Windows client and deskphone.

I know the webclient is fine however it works using Web RTC so maybe able to find is way around to connect.
