  • PBX, fully compatible with Asterisk® Open Source PBX software

Asterisk® is a complete PBX software. It runs on Linux, BSD, Windows (emulated) and OS X and provides all of the features you would expect from a PBX and more. Asterisk® does VoIP 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, and 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.

Asterisk® needs no additional hardware for VoIP, although it does expect a non-standard driver that implements dummy hardware as a non-portable timing mechanism (for certain applications such as conferencing). 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 like Odin's OTX compatible devices. Odin has single, quad and octi span T1 and E1 interfaces for interconnection to PRI lines and channel banks also a complete system integration all-in-one Asterisk® enable devices like Alvis-4-CSI and Alvis-8-CSI.

For interconnection with the cellular network (GSM or CDMA), Asterisk® can use the Celliax channel driver or chan mobile that is in the trunk now and there is also an unofficial back ported version.

The 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.
