OK, here's what happened. I had the same issue of the phone resetting when a call came in, I thought it was a power issue and through some testing it was not. Here's the fix...Menu \ system settings \ enter pin (if you haven't changed it it is 0000) scroll to factory default and reset. This fixed the problem somehow for me, make sure to write down any impotant messages because it will erase everyting (silly me). I hope this helps.

There is a way to override and reset... I think you need to press *67# when in the system pin area via menu. Confirm this first though. There is a way to do this though- then you reset it to 0000- google it and you will find the answer-

To reset the Gigaset 2420 Pin
At "System Settings" in the Menu press *65# then press the Select button.
"System PIN Reset" will be displayed (if the PIN was not already the default).
The default PIN is 0000.

I had the same issue a while back and I believe a new power supply fixed that problem. If you know anyone with a multi-meter and they know how to use one they can tell you if your power supply is bad or not putting out enough voltage. I believe this system requires 12 volts and 400 milliamps it will say on your current power supply.

The most common issue here is that the touch screen is defective, to replace this can equal the cost of a new phone of another brand.
