Have you already reviewed the hardware manual how to connect microphone and speaker?

Refer to the description of ATD command how to setup a mobile originated voice call.

Without connecting to microcontroller or PC you can only receive calls to GSM SIM300 from another phone or mobile but you cannot make calls. To make calls from GSM SIM300 you need to connect to microcontroller or PC to issue the ATD+xxxxxxxxxxx; command for voice calling. Even a tiny micro with 8 pins and UART is enough to send the command to GSM module or else PC can be used.
