CID on a 7730 reqoires 3 things, CID service from the phone company, programming on the sytsem, and a CALLER ID CARD. The card can only be added to TA-624/824, TAW-848, TD-816/1232, and TDA/TDE/NCP sytsems and has a part number ending in 93.
If it never worked from "day 1", then I'm guessing you either didn't order the card, or you forgot to inform your installer that you wanted CID turned on. Only the 50g and TA-824 models came with CID in the U.S.
Before accepting the phone company's word, make sure another basic caller id phone can display CID. If it does then check the programming in the phone's set up menu to be sure it hasn't been mistakenly disabled.
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?
