Caller ID? No problem, 27 Jun. 2012
I bought this item to use CallerId on a BT landline. Although this is rumoured to be 'difficult', I managed it with this
modem first time. The AT control strings are: AT+GCI=B4 (sets country to UK) AT+FCLASS=8 (sets voice mode) AT+VCID=1 (enables caller ID).
In fact, maybe only the last one is needed - anyway, it works fine...
