Asterisk
Asterisk is an Open Source, Private Branch eXchange (PBX) and
telephony
toolkit. It is a hybrid TDM and packet voice PBX and IVR platform with
ACD functionality. It is, in a sense, middleware between Internet and
telephony channels on the

telephony. Asterisk also has a vast amount of support for
traditional PSTN telephony, as well.

and Digital Interface cards from Digium, QuickNet Internet PhoneJack
and LineJack, any full duplex sound card supported by ALSA, OSS, or
PortAudio, any ISDN card supported by mISDN on Linux (BRI), The Xorcom
AstriBank channel bank, and VoiceTronix OpenLine products.
