I’ve been playing with hot desking via log in/out. All that works fine, no issues there.
My challenge is that when using traditional extension mapping where you map an extension to a phone manually, you can tell the phone to substitute your extension with a different one (with respect to BLF buttons). This lets your BLF setup avoid having a BLF on your own phone for yourself which is annoying.
I see no way to do that when using hot desking. Not sure why this couldn’t work, so hoping I am just missing something.
