Running a Meridian Option 61C running release 25.4 software. I am attempting to upgrade a user from a M2008 to a M3903. When I out the set and copy an existing M3903 to that new DN and TN and try to upload the set, it is coming back with something like, unknown SL-1 response, or no response. And the set behaves like it's dead, except for the time displaying on it.
