EX200 can convert
DTMF or ETSI FSK caller ID data to Bellcore FSK format. If
the user has an equipment, which can receive caller ID with
Bellcore FSK format (such as cordless phone on US market) ,
but the service provider only give DTMF or ETSI FSK format
for caller ID (such as Taiwan, India, Saudi Arabia…), then
this unit can convert DTMF or ETSI FSK caller ID data to FSK
format. The phone can display the incoming call numbers.
