Spelling: Asterisk
Asterisk is an open source Linux software for PBX and designed for
small installations (25 users). It runs on Linux and provides all of
the features you would expect from a PBX. Asterisk provides voice over
IP in three protocols, and can interoperate with almost all
standards-based telephony equipment using relatively inexpensive
hardware. Asterisk is not designed for ease of use/administration, it
requires a good amount of scripting and command line knowledge.
Asterisk provides Voicemail services with Directory, Call
Conferencing, Interactive Voice Response, Call Queuing. It has support
for three-way calling, caller ID services, ADSI, SIP and H.323 (as
both client and gateway). Asterisk was originally written by Mark
Spencer of Digium, Inc. Code has been contributed from open source
coders around the world, and testing and bug-patches from the
community have provided invaluable aid to the development of this
software.
While a gateway provider is needed for access to the PSTN, Asterisk
needs no additional hardware for Voice over IP. For interconnection
with digital and analog telephony equipment, Asterisk supports a
number of hardware devices. Asterisk supports a wide range of TDM
protocols for the handling and transmission of voice over traditional
telephony interfaces. Asterisk supports US and European standard
signalling types used in standard business phone systems, allowing it
to bridge between next generation voice-data integrated networks and
existing infrastructure. Asterisk not only supports traditional phone
equipment, it enhances them with additional capabilities.[EditText] [Spelling] [Current] [Raw] [Code] [Diff] [Subscribe] [VersionHistory] [Revert] [Delete] [RecentChanges]
