Overview
makes Asterisk more accessible• simplifies configuration of most
common Scenarios • more familiar terminology • proper defaults
complete system• new releases upgrade everything
(OS, Asterisk, etc:)• single XML file stores configuration of
entire install
targets embedded hardware• build a PBX with off-the-shelf
components• low power-consumption
scales up to larger tasks with morecompetent hardware and softwareextensions

Market Environment
Similar Projects Differences to AskoziaPBXAsteriskNOW, Trixbox, Elastix• complete systems with easy to use
GUIs• much too large for smaller hardware platforms• too much expected of people new to Asterisk &
Linux
Open Source AstLinux
• targets embedded hardware • missing a user-friendly GUI
Com
mercial
FRITZ!Box Fon• excellent option for SOHOs• built-in traffic shaping, routing, firewall
and modem• user-friendly
• limited configuration options• fixed, non-upgradable hardware components

Standing on the Shoulders of Giants
11
Roadmap
support for integrating AskoziaPBX with back-end authentication / storage
permanent storage interface• attached storage devices can be
defined to support “extended services“• ...permanent logs, full voicemail
system, additional audio packs
Technical
improve network interface features:• automatic detection• multiple interfaces will be bridgable• VLAN support• WLAN support
Configuration
expand incoming call routing options• DID / DDI• ACD Call Center Features
Telephony
allow AskoziaPBXs to easily be clustered or coupled

Community / Support• public svn, so far a single committer• project's target audience is end-users rather than programmers• the gold that our community produces:
- interface, device and provider interoperability reports- ideas for missing features expected in other regions / cultures- Translations
• community has donated and lent equipment for testing• particularly evident in getting initial ISDN support implemented• continued cooperation with isdn4bsd project in adding additional
support for unrecognized cards
• IKT ported efficient echo-canceller from Linux to FreeBSD, now publicly available High international visibility and
recognition (e.g. Japan)
• One full time developer at IKT
• Support team of 5 VoIP-and Telecom-specialists at IKT
