The reason I upgraded is that sometimes although telephone provider signal is active incoming voice calls are diverted directly although divert always is deactivated !!. Very annoying so upgraded to newer firmware but got the same issues with this newer firmware.
If you still have warrenty for phone go to service - seems to me like some hardware issue
