Asterisk & Trixbox Expertise
Asterisk is an open source telephony project. Asterisk is software that turns an ordinary computer into
a voice communications server. Asterisk powers IP PBX systems, VoIP gateways, conference servers and
more. It is used by small businesses, large businesses, call centers, carriers and governments
worldwide. Asterisk is free and open source.
Why an Asterisk based PBX? Asterisk has a number of core strengths that set it apart from other telephone systems.
Serious Cost Reduction. Asterisk can typically be installed for about half the
cost of a traditional system. For large scale systems the saving can be even greater.
Control. Asterisk allows a business to take control of their phone calls. Once a
call is received by Asterisk virtually anything can be done. Asterisk provides a level of granular control
normally only associated with the most expensive of systems.
Integration. Asterisk can be integrated into your existing business systems such
as Microsoft Outlook, CRM and ERP systems. Integration is probably Asterisk's greatest strength. Being able
to integrate your business systems directly with your phone system changes how you view and use your phone
system. See the page on Integrating Asterisk for a discussion on how Asterisk can be integrated with
business systems.
VoIP. Asterisk was built to handle VoIP calls. Significant savings can be had by
using Asterisk to send all inter-office calls across the Internet or ideally your
corporate WAN or private IP network. As well as reducing external call costs by using Mobile Telephone
Gateways (aka GSM Gateway, SIM dialers...) and accessing flat rate national call costs. It is not uncommon
for the savings in call costs to pay for the acquisition of an Asterisk PBX System.
No Lock-In to Proprietary Systems. Obtain support, accessories and upgrades from
a variety of sources. Their are dozens of third party applications which can further extend the
functionality of Asterisk and a surprising number of them are free. Telephone handsets are standards based
(SIP) and can be re-used on other SIP based PBXs.
Reduced Cabling Costs. VoIP based telephone calls are not just for making calls
over the Internet. Asterisk can also use VoIP for calls within the office using your existing
LAN lines. When wiring a new office, this can lead to considerable savings as only one set of cables need to
be laid.
