I want to Know my modem support caller-id and show number or not I use this AT-command:

 AT+FCLASS=?

I know if that response contains 8 support voice but if modem dosnt support voice it means cant support caller-id too? I use Conexant USB CX93010 ACF Modem

Answer 1

I assume you by caller-id means the supplementary service called CLIP - Calling Line Identification Presentation (for GSM/UMTS networks). You can check if your modem supports this by running AT+CLIP=?. To enable +CLIP: ... unsolicited responses after RING run AT+CLIP=1. Read 27.007 for more details.
