One of my customers is having a strange issue with EM. When anyone tries to use EM, they get an error on the phone saying -Device does not exist. The user has an EM profile, the service is configured and the device they are trying to log into is EM enabled. This was working when the phones were installed. I tried testing this with one of the profiles and an IP communicator that is set up for EM and I got the same error.
Any ideas why? I looked up the error and all I saw was a vague description in the developers guide. This is a 6.1(2) system.
