If you are unable to see the above a Firewall on the PC is blocking the BToE Discovery

 

If you can see the above but BToE still not offers to pair and prompt the user to enter their credentials on the Skype for Business client then a local policy or as an example, Symantec Endpoint Protection blocks the communication.
