ASTERISK PABX |
|
Asterisk VoIP SIP |
Asterisk is a complete PBX in software.
It runs on Linux, BSD, Windows and OS X
and provides all of the features you
would expect from a PBX and more.
Asterisk does voice over IP in four
protocols, and can interoperate with
almost all standards-based telephony
equipment using relatively inexpensive
hardware.
Asterisk provides Voicemail services
with Directory, Call Conferencing,
Interactive Voice Response, Call
Queuing. It has support for three-way
calling, caller ID services, ADSI, IAX,
SIP, H.323 (as both client and gateway),
MGCP (call manager only) and SCCP/Skinny.
Check the Features section for a more
complete list.
Asterisk needs no additional hardware
for Voice-over-IP, although it does
expect a non-standard driver that
implements dummy hardware as a
non-portable timing mechanism. A single
(or multiple) VOIP provider(s) can be
used for outgoing and/or incoming calls
(outgoing and incoming calls can be
handled through entirely different VOIP
and/or telco providers)
For interconnection with digital and
analog telephony equipment, Asterisk
supports a number of hardware devices,
most notably all of the hardware
manufactured by Asterisk's sponsors,
Digium. Digium has single and quad span
T1 and E1 interfaces for interconnection
to PRI lines and channel banks. In
addition, single to quad port analog FXO
and FXS cards are available and are
popular for small installations. Other
vendors' cards can be used for BRI
(ISDN2) or quad- and octo- port BRI
based upon CAPI compatible cards or HFC
chipset cards.
Lastly, standalone devices are available
to do a wide range of tasks including
providing fxo and fxs ports that simply
plug into the LAN and register to
Asterisk as an available device.
The current release version of Asterisk
is 1.2.4.
