Connecting Asterisk to the PSTN - a tutorial
Asterisk supports a number of connections to a PSTN network, being able to work as an ordinary PSTN PBX or as a multiprotocol VOIP/PSTN PBX and gateway.

Asterisk allows you to seamlessly bridge circuit-switched telecommunications networks with packet-switched data networks. Because of Asterisk’s open architecture (and open source code), it is ultimately possible to connect any standards-compliant interface hardware. The selection of open source telephony interface boards is currently limited, but as interest in Asterisk grows, that will rapidly change.† At the moment, one of the most popular and cost-effective ways to connect to the PSTN is to use the interface cards that evolved from the work of the Zapata Telephony Project (http://www.zapatatelephony.org).
