Troubleshooting:
BToE Discovery is sent from the Phone at an interval of around 3 seconds to the PC connected to the PC Port off the phone to the BToE App running on the PC to discover the connection.
Wireshark filter udp.port == 2081
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 does still not offer 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.
