Hey Guys,
Looks like the newest firmware was released (2.1.5.4) for the UC360. I went to see what has changed in this "Minor" release update, but got a chuckle from the release notes. Looks like all they did was take the 2.1.5.3 release notes and replace the cover and table of contents page. I'm gonna reach out to Mitel on this to see if I can get an answer on what was updated.
Thanks,
