Caller ID - Regional Differences

Regional Differences

Different countries often use different standards for transmitting caller ID. As a result, phones purchased in one country may not be compatible with the caller ID standard use when the phone is used in a different country. For example, US uses Bellcore FSK whereas Taiwan uses ETSI FSK so a phone purchased in the US will not understand Taiwan's caller ID standard. There are even cases where individual state/provinces will use different protocols within a country. There do exist, however, caller ID converters that will translate from one standard to another. Below is a list of countries and the caller ID standard used:

United States Bellcore FSK
Canada Bellcore FSK
China Bellcore FSK
Hong Kong Bellcore FSK
Ireland ETSI FSK V23 (ETS 300 659-1) Ring Pulse Alert Signalling. Data sent after first short ring.

Famous quotes containing the word differences:

    No sooner had I glanced at this letter, than I concluded it to be that of which I was in search. To be sure, it was, to all appearance, radically different from the one of which the Prefect had read us so minute a description.... But, then, the radicalness of these differences ... these things ... were strongly corroborative of suspicion.
    Edgar Allan Poe (1809–1849)
