Asterisk - Telephony system
Asterisk is a complete PBX in software. It does
voice over IP in three protocols, and interoperates with almost all
standards-based telephony equipment using relatively inexpensive
hardware. Asterisk provides Voicemail services with Directory, Call
Conferencing, Interactive Voice Response, and Call Queueing. It also
supports three-way calling, caller ID services, ADSI, MGCP, SIP and
H.323 (as both client and gateway).
The system needs no additional hardware for Voice over IP. Asterisk
connects with digital and analog telephony equipment through a number
of hardware devices, including that manufactured by Asterisk's
sponsors, Digium. Digium has single and quad span T1 and E1
interfaces for interconnection to PRI lines and channel banks. An
analog FXO card is available, and more analog interfaces are pending.
