Endpoint Manager does not create y000000000096.cfg + Missing XML-API in BLF type for Yealink T54W

I’m setting up hotdesking with Yealink Phones. In endpoint manager, for Yealink T54W, the BLF type XML-API is missing.

I also found out that the default profile is not generated for T54W. When configuring hotdesking, the default profile is used to provision phones with a Login Button. A bunch of files are generated in the TFTP folder (y000000000000.cfg, y000000000002.cfg, etc). When looking at the apache logs, when I try to auto-provision a T54W that is not in the list of configured phones in Endpoint Manager, I see that the phone tries to download a file named y000000000096.cfg. This file is not created automatically by Endpoint Manager, so the T54W does not get the “Login” button. If I copy the file from another yxxxxxxxxxx.cfg files and rename it y000000000096.cfg, the default provisioning works and the login button is added. After loging in, the phone configures itself correctly with the default profile, but since I do not have the XML-API blf available for T54W in Endpoint Manager, the Login BLF cannot be added to the template, so there is no way to logout the phone.

Endpoint Manager 15.0.43.1
