Question about Siemens Gigaset 2420 Cordless Phone

1 Answer

Line cut off problem

When I answer the phone or try to make a call, the line seems to lock up then it disconnects. I have 3 phones in the house, when I disconnected the 2 line Siemens Gigaset phone, the problem went away. I tried plugging in just one of the lines at a time to the Gigaset, but still had the problem. Does this sound like a line or phone problem?

That is a common problem with this model, normally happens after a storm passes through. Unfortunately there is no easy fix for on site, it would need to be sent in for repair or replaced. You can google Siemens Cordless Repair to find service facilities.

Sounds like your phone or line is now short circuit and is holding the line so it appears busy to incoming callers. Try disconnecting the pnone and line right up to the incoming point of your house to find the problem.

Most newer fax machine seem to short line 1 and 2 together and this will cause a VOIP modem "called an eMTA" to go off hook. Your fax machine should have come with a phone jumper that has only a single line "2 wires inside it", you should be able to use that jumper to attach your fax machine to your house phone wiring. If you use a standard phone line jumper it has both lines "4 wires" and can cause your eMTA modem to go off hook which could be why it was disconnected.

Meridian M7310; just installed replacement phone (used); line 3 disconnects when answered. Lines 1 and 2 work fine. They are in the loop. Line 3 is dedicated fax incoming but can be used as outgoing phone.

Normal 0 Hello, Gary.

Disconnect power and cables from all phones and faxes on the line 3. Wait 15 minutes and reconnect the line again, one at a time. See if the Meridian works. If not, it could be faulty.

Hope this helps.

Suspected short in RJ-11jacks.

Try temporarily disconnecting your security system. They occasion have intermittent problems communicating and this is what may be tying up your phone line. Most shorts do not happen with a timed rhythm that you are having.

We have an older AT&T spirit phone system, sometimes line 1 will not work, I disconnect line 1 from the phone system box and plug back in, I then get a dial tone but the line will not disconnect, this...

There is most likely a problem with your control unit and the CO line 1 will not disconnect. However, to absolutely eliminate all other possibilities, try swapping phone lines 1 & 2 and see if the problem stays at line 1 (which will now be a different phone number) or if the problem moves to line 2 which would indicate a problem with the wiring to the control unit.

Hopefully you do not use all the phone lines in your system and you can move them all down one slot. (line 1 becomes line 2, line 2 becomes line 3 etc...) and just stop using line 1. Otherwise you will need to find a replacement control unit.

Just some Tips - Do you have any other phones or fax machine in the house? Check to make sure they are all hung up or press the off/ hang up button. If so, disconnect them until one brings back a dial tone when disconnected Also try cleaning the charger contacts with an eraser to the charger sends a signal that the phone is hung up.
Hope this helps!
