Prepare a computer with PCI slot

Consider the cost and compatibility, normally I will use Dell desktop or server.

Install telephony interface cards into your computer

Telephony interface cards are PCI or PCI Express expansion cards that connect computers running Asterisk directly to legacy phone lines, phones and phone systems. The cards convert the legacy signaling and media into Asterisk’s internal formats.

I chosen Digium cards, because Asterisk is provided by Digium. A lot of cheaper alternative cards, I just don’t want to facing compatible issue.
