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.
