For me it just went from bad to worse... 7941 phones POE with bullseye boot. Tried the 1 2 3 4 5 6 7 8 9 * 0 # reset - no luck.  Rebooted - bullseye again, failed to register. Next tried 3 4 9 1 6 7 2 8 5 0 * #.  Both indicators flashed alternate red...

Windows Server 2012 R2 X64 - I downloaded and installed 32-bit Java jdk-6u45-windows-i586.exe which is the last version of JRE 1.6 and it worked.  Java 1.7 does not work.
