Caller id hi i bought a siemens gigaset 4215 from USA a few years ago.Ihave now brought it to India.The problem is that the caller id feature does not work although i have a caller id subscription and is working on other phones. I think the problem may be due to differenr caller id systems in USA and india i.e,fsk and dtmf.Is this phone only fsk compatible?is there any converter with which i can receive caller id on this phone?Please enlighten me on this issue ASAP.thanks

It is my understanding the caller ID feature comes as part of your telephone service and your phone only displays what comes through. So either you changed the subscription which means you dropped the Caller ID feature or your BT plan does not have it anymore. Best to call BT and confirm.

Hello Samiran mandal, here is a solution.I purchased one cordless telephone (Siemens Gigaset) in Germany. I also had the same problem, caller-id did not work. I purchased this telephone because we can set different ringtones for different caller groups. But, if caller-id doesn't work, this feature also doesn't work. I had gone through internet and finally found that CA electronics, Bangalore has it and got it through courier (I live in Pondicherry). It worked flawlessly for two years. Then it stopped working. For 'no reason' I ordered for a 'caller-id' unit on ebay for Rs.75/- (+ Rs.75 shipping). I just got the unit and fixed it to my line. Very very surprisingly, my cordless telephone is now showing caller info. This is a real surprise to me. By the way, caller-id unit is "Eurotel" make, DTMF/FSK caller-id. I feel this is very nice solution. The 'caller-id' unit is nice (backlit display) and also there is no need of converter for using the caller-id feature of your foreign telephone. I connected caller-id between the line and telephone. That's all. Enjoy.

The source of my caller ID not displaying was a faulty ADSL filter.
For some reason my ADSL filter blocked the caller id information - but worked fine otherwise.
When I changed the filter the caller ID worked fine again.

Does it say any of these on the display
Extern. call -means not arranged with service provider. Contact your service provider.
Withheld- Caller is withholding caller ID information.
Unavailable -your phone is not setup to display caller is with your provider.Contact them.

In addition your phone provider must support CLIP,CLI and CNIP. Confirm with your provider.

Well if the phone has been bought abroad and being used in India you will face this problem. this is because of the format of transmitting the caller id info being different. In USA it is STF and in India it is DTMF. You need a convertor in the phone line which is DTMF to STF. IF you find onw in Delhi pl let me also know.

Were those other instruments purchased in India? The problem is that the U.S .uses a different"signal" to send caller ID than India.

Even at its factory defaults your Siemens handset should be showing the caller id after the second ring. Look at your time and date on the phone, if they are not accurate then the caller id signal is not coming through since when activated caller id will not only give you the caller information, but it syncs with the telephone companys clock too. If I were there, I would take a phone that is known to have its caller id working and plug it in your line and see if caller id shows up on it. If it does show caller id, then there is something wrong with your Siemens base. If it does not, then your phone company dropped the ball and caller id is not activated. Then I would take the Siemens phone to another line (neighbor or friend) that has working caller id and plug my Siemens into it and see if it shows up. Doing all that will isolate your problem, I guarantee it.

For people who have purchased cordless phone in usa and caller id is not working they should purchase fsk to dtmf converter at any local phone shop and caller id will start working.

Here is the article on various frequency used by various countries for caller id.

Hope this will help you out.

Detailed Product Description

There are 3 major caller ID specifications in the world: DTMF, ETSI FSK and Bellcore FSK. When users buy a foreign telephone devices(such as cordless phone, fax machine or computer telephony interface), may encounter the problems of non-match for caller ID standard. This will cause the device unable to display the caller ID. EX220 can solve this problem easily. This product can receive all 3 kinds of caller ID format, and convert to FSK(Bellcore or ETSI selectable) to match foreign telephone's standard.
EX220 has a rechargeable battery inside the device, during idle status, it gets power from the telephone line and recharge the battery, so no need to use or replace battery. Just plug one end to telephone line, and the other to the telephone device.
For example, if you live in Netherlands, Saudi or India, the caller ID standard is DTMF. You purchased a cordless caller ID phone from US(which uses Bellcore FSK standard), or from Germany(which uses ETSI FSK standard). You won't be able to use the caller ID feature. In this case, just get one EX220 and connect it between the telephone line and the cordless phone, your cordless caller ID phone will display the caller's number immediately.
Remark:
1. Telephone sets for UK and Japan standard are not applicable.
2. In some countries, users must subscribe to Telecom for caller ID service

I too purchased an Uniden phone for India. Everything except the caller ID works fine. The caller ID wont work as the technology used in India is different. Try purchasing a FSK to DTMF converter or a separate caller ID box.
