As @arun kumar non ascii mentioned you can answer the call using ATA .

You can also know the number of person calling you (i.e. Caller ID) by executing AT+CLCC

You can also set your modem to auto answer the call using ATS0=<n> , where <n> is the number of rings after which you modem should auto answer the call.
