Go to the GSM section. Bunches of threads there on how to interface with cell phones.
A search using the keyword 'dialing' brings up a few decent hits too.

Nothing special needed. Connect to the serial port of the phone with an appropriate level converter and just send ascii AT commands, like ATD1234567890.

Now I don't remember if a semi colon is needed for data calls. I think is for voice call.

But this is the general idea.

Rest is directly related to the hardware you are using both ways.

There are other similar single-chip modems.
