Hi, we have upgraded a 7.0.1 installation to 7.1.2a(SU1).
I do not exactly know what firmware version they had before, but since we did the upgrade it looks like this phones have a memory leak or something... after a while, the phone get's one way audio or some noise in the calls. When you reset the phone, it's o.k. for an amount of time, and then it starts again.
We upgraded than to 8.1.2...no change, same with 8.0.9... We also switched back to 7.0.1, but i think it must be a firmware issue...
We also have some 7942/7965... they are all fine...
Any ideas about this ?
