Since new area code rules came into effect requiring area code for local calls, when a caller pnones in the phone adds #1 before the number in the caller ID thus making it a long distance call, so if you want to call the number back you have to save & edit to get rid of the 1, is their any setting to stop it from adding the 1
Talk with your service provider
if the number 1 is placed before a local number then logically when calling that number, the number would be recognized as a local number and be charged as such
Form what you say , if the number was from a caller in a different state and the number was prefixed by say 6 then the system would recognize that as a long distance call
again talk with your service provider and if accurate contact your state governor or senator and make an issue of the law requiring the prefix number on caller id

Hi,
I don't think the problem is the FSK vs. DTMF. The manual even states that the caller ID is generally received after the second ring. This is true in America. I lived in India for four months and I never ran into the problem there so... I just can't say how your provider sends the caller ID. It may be that the line is being interfered with. Do you have a DSL line attached to the same device. If so make sure that there is a filter between you phone and its connection.
I am assuming that you tested your line with the other equipment connected to the same location. You may want to reduce the problem to the simplest configuration by connecting directly to the line only no other equipment. If it works add the other equipment until the caller ID stops again. Then you know what is interfering. If you have a monitor set you could listen to the DTMF being sent make sure it is coming between the first and second ring. It is audible if it is there. If you are answering on the first ring you will not see caller ID you have to wait till after the second ring then you should see it, If BSNL is sending the same as American systems. Good luck Z

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?

You have a 7730 PHONE. The system is not determined, but in analog going forward it could be a TA-624/824 or TAW-848.
If you have a TA system, it requires programming http://www.fixya.com/support/t2436730-caller_id_stoped_working_dont_know_clear
