Problems with 79(46)x Phones after Upgrade from 7.0.1 to 7.1.2

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 ?

Kind regards

Steffen

Try loading the same you have on 7942/65.

...not possible.

The 7940/60 are EOL, latest Firmware is 8.1.2.

The latest Firmware for 7945/65 is 8.5.2sr1

Then you have to load latest FW, and complain to the TAC.
