Siemens Gigaset 2420 corded unit resets when calls received

Corded unit appears fine until incoming call comes in and unit resets. You cant answer phone calls because unit resets. Other phones on the same line can pick it up, then Siemens can pick up line. LCD display goes blank when unit resets. Could be a overload from ring voltage coming in from line while ringing. Anyone out there have any experiences like this?

    I have the same phone with the exact same problem it is driving me crazy. I have tried everything and think it may be the power supply. I have 3 of these phones and they all do the exact same thing when plugged in.

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.

Your caller id log is full, you can fix your phone by pressing the Calls button, then the delete button over and over until it is empty. This will fix your problem without deleting all your programming.

Phone does not ring

Time to get new phones. You incoming wires are not operating on the base of the phone. It is called the 'ring-side' or 'red' wire. Unless you know where the break is, you cannot fix it. because it happens on all the has to be broken in the base that serves them all. This isolation is furthered by the fact that a corded phone works fine on incoming calls, so it is not in the line to the building, broken on the ring side that is. Happy phone hunting!

I can not take incoming calls i can not answer on my phone the line does not flash or ring all other phones on the system can

Two things need to happen. If the line appears on you phone (press program and the button where it appears on other phones) and if it does, then your phone needs to be added to the ICD group with ringing. It's best programmed from the Maintenance Console vs. a phone. Your Panasonic service tech can do it in a matter of minutes.

I want all incoming calls to come through my extension only.

What it sounds like you want to do is restrict the automatic system answering to certain extensions. This is done via feature code 204.

To identify the lines on which outside calls should be answered by the system:
  1. Press feature +(00)+(system program)+(system program)+#204
  2. Enter the two-digit system line number of the desired line.
  3. To assign or unassign the line, press (Next Data) until the appropriate value appears.
    1 = Assigned
    2 = Not Assigned (the factory setting)
  4. To identify another line, press (next item)or (prev. item) until the line number appears on the display. Then repeat Step 3.
  5. Repeat Steps 3 and 4 for all the lines that you want to identify.
  6. Select another procedure, or exit programming mode.
