I just purchased a slim caller id phone. The caller id is not working. The phone company advised that the service is connected.

Please call your phones service provider, they may charge for this service. Just because the phone is capable of caller ID function doesn't mean it is a free service.

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.

Caller ID on landline phones relies on signals from the telephone service provider. Some companies charge extra if you wish to enable the service, others include it automatically, so you need to check with them first.

Even if you have caller ID enabled, callers can choose to withhold their number. Large companies which make lots of outgoing calls (especially cold callers) often have their service set to automatically withhold their number. In many countries, all other callers can choose to do so by prefixing all dialled numbers with a short code, e.g. in the UK it's 141. Mobile phone callers can usually alter a setting on their handset so that caller ID is withheld when making outgoing calls.

• Did you fully charge your phone? - Make sure you fully charge for 16-24 hours .
  
  
• Is the battery old? - Replace the battery.
  
  
• Is the electrical outlet switch turned on? - If you are using AC (electrical) power, make sure that the unit is connected to a non-switched electrical outlet.
  
  
• Are the connecting wires tight - Unplug the AC power converter from the unit and plug it back in.
  
  
• Do you have Caller ID service with your telephone company - In order to receive Caller ID records, you must subscribe to the standard name and number Caller ID service available through your local telephone company. If the Caller ID works for normal calls but not on Call waiting calls, then you must contact your phone company to get the combined CID/CW service.
  
  
• Caller ID shows up after second ring - Be sure to wait until the second ring before answering. Caller ID signals comes through after the first ring, if caller pick ups phone too soon Caller ID signal will not be transmitted to the handset.
  
  
• Confirm that caller ID is still working on that particular line by checking another phone on the same line - If Caller ID is not coming through contact your phone company provider.
  
  

If this does not fix your problem, contact your authorized Service Center.*

Please download this manual, and study e.g on page 21 About caller ID If you subscribe to caller ID service from your local telephone company, this feature displays the name and telephone number of the caller before answering a call (even when you are on another call). The caller ID features of this product will work only if you subscribe to caller ID service and both you and the caller are in areas offering caller ID service, and if both telephone companies use compatible equipment. Contact your local telephone company if: • you have both caller ID and call waiting, but as separate services (you may need combined service), • you have only caller ID service, or only call waiting service, • you do not subscribe to caller ID or call waiting services but wish to try them. There may be fees for these services, and they may not be available in all areas. This product can be used without subscribing to either caller ID or combined caller ID with call waiting service, although the caller ID features of this product will not function.

Hello,

Found this on the VTECH support site regarding your model:

Tip 1 of 1

Caller ID and Call Waiting ID are subscription services, available from most local telephone service providers. You must subscribe to these services in order for the features to work on your phone. Contact your local telephone service provider for more information.

In addition, your caller must be calling from an area that supports caller ID.

Both you and your caller’s telephone service provider must use compatible caller ID systems.

If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY phone jack that has a phone. The DSL signal can cause caller ID disruption, static, noise and other issues on your line. DSL filters block the high frequency DSL signals from being transmitted to the telephone. If you are not using the DSL filters provided by the telephone company, this will cause static/noise and possibly caller id issues on your phones.

In most cases, we recommend you connect the plug end of the DSL filter into the telephone jack, then connect a telephone cord between the filter and your phone.

Please contact your service provider to obtain DSL filters and installation information.

Caller ID and Call Waiting ID may not be available for every call. Common reasons are incompatibilities between your and your caller’s service, transmission errors and answering calls before the ID data is received.

In addition if you would like to contact them or get more info on your phone, then use this link:

you can do that through your network service provider

Is the phone FCC approved for use in the US? Does the model purchased in Singapore use the same Caller ID algorithm as US phones? Have you tested a known good caller ID capable phone at your location to make absolutely sure the caller ID is actually turned on?

US phones use Bellcore FSK caller id. India uses DTMF caller id. Buy a DTMF- FSK converter at a telecom shop.

In USA, CANADA, telephone company uses FSK for Caller ID detection while Indian Telecom companies uses DTMF standard. this is the mismatch and reason for caller ID not working.

u need to purchase seperate caller ID for it.
