Can't connect IP phone to server

I've recently purchased a Siemens Gigaset S450IP phone (UK) The phone works fine as a normal house phone, but I have been unable to get it to connect to the server. I followed all instructions on setup and checked settings on router, but to no avail. After days of trying and getting my son, who works with computers, to try and sort the problem, we came to the decision that the base station must be faulty or there was a problem with the firmware. Unfortunately as I can't connect to the server, I can't update firmware. Thinking it might be a problem with the base station I obtained a replacement phone. However the replacement has the same problem.
My router (safecom SWART2-54125) appears to be working and registers the IP address of the phone, but if I do a ping test it is inconsisent and rarely goes through without dropping packets. Even thought the router is obviously assigning the phone with an IP address I cannot access settings through the web browser as the manual says. I am getting messages on the phone saying, "Provider registration failed", "cannot access server" and "check IP settings". We have altered settings on the router to see if it makes any difference, but doesn't. I've changed settings to static IP address, have tried resetting the base station, handset and router. Thinking it could be a connection problem, I changed the ethernet cable. None of these made any difference. I'm at a loss and wondering if it is something to do with the settings, or a problem with either the router or the phone. HELP

SOURCE: Problem Siemens Gigaset 4000 and 4200

If you had a storm, and the only handset that works shows line in use, then your base has gone bad and needs repair. The reason the phones are flashing base 1 or something to that effect is because they don't see the base anymore, which typically means no phones will see your base, so its odd that one phone is actually seeing the base. Either way, you can try re-registering the phones to the base, but if you get the line in use after they register (if they will register), then your base is bad. If they won't register, your base is bad. For additional assistance you can go to

SOURCE: Merging 2 siemens gigaset 4215 systems (one base with 2 phones + 2 phones)

If you're trying to get 5 handsets to work with one base, it won't work. The 4215 can only handle 4 handsets, the base handset plus 3.

When I had to replace the base of my 4 handset system, the base handset still worked. Therefore I had an extra handset which couldn't be used. So I decided to buy another base. Now I have 6 handsets which can be grouped 4,2 or 3,3.

Siemens Gigaset 4200 Cordless keep searching for base

The handset should be returned to the charging station, let it set for a few seconds. If this is a satellite phone, make sure the main phone "base unit" is connected to phone outlet and plugged in. After the phone has established its physical connection with the base again you can remove it and use it like normal.

Hello Diederik,

Just had a look at my Gigaset C2, where I can just follow the menu, same on my Gigaset A2. Have you got a screen display with menu options?

Kind regards,

Handset won't work

I went through this exercise with a Siemens Gigaset 8800. The solution is to DE-register the handset first. Then register it with your base. This function can likely be accessed in the handset menu. The phone you purchased is apparently still registered to the previous user's base.

Want to unlock Siemens Dual Phone DP450

How To Unlock Tesco Internet Phone Siemans DP450

Unlock your Tesco DP450 IP Phone to use this with other VoIP providers.
Gigaset Communications have created a process that enables Tesco Internet Phone subscribers with Siemens Dual-Phone DP450 to unlock the phone from the Tesco Internet Phone service. This will enable the phone to be used with other Internet Telephone services. This follows the recent news that the Tesco Internet Phone service is to be ceased from April 26th, 2010.
This is an approved method for unlocking the Siemens Dual-Phone DP450 defined and released by Gigaset Communications, the original supplier of the phone to Tesco. If this procedure is not followed exactly your phone might not work anymore. In this case Gigaset Communications cannot accept any warranty claims.

Unlock procedure
Your Phone should have the latest released Tesco software version, else this unlock procedure will not work.

On your handset:

Select and press OK Enter the system PIN (0000) and press OK
The base station establishes a connection to the internet or a local PC.
YES Press the display key to start the firmware update. If no update is needed, this will be displayed.

To unlock the WEB interface of the DP450, you need to enter the following service code. Please use the exact code as is described below, else your phone will not work anymore.
SETTINGS > BASE 94762001 (Now "Eeprom" must be displayed)
Insert the following number sequence: 01778 06183 06191 Press OK to finish the programming. "Saved" must be displayed on the Handset.

Then release the phone to be able to upgrade it with the latest Retail firmware version.
SETTING > BASE 94762001 (Now "Eeprom" must be displayed)
Now insert this number sequence: 04850 04351 04864 Press OK to finish the programming. "Saved" must be displayed on the Handset.

After this procedure you can upgrade your phone to use the latest retail firmware version.
Select and press OK Enter the system PIN (0000) and press OK
The base station establishes a connection to the internet or a local PC.
YES Press the display key to start the firmware update.

Please Note: The firmware update can last up to 3 minutes.

Your Phone is by default configured to use the Internet Telephone service, if you want to change this to set the default to the land line you need to change this in the web interface from your phone. How to do this, download the Gigaset S450 IP manual from the Gigaset web-site URL: ... nuals.html

Line cut off 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.
