1 Compact Open Source Soft PBX for VoIP Solutions in SOHO and SME Environments Prof. Dr.-Ing. Diederich Wermser Michael Iedema (BSC CS)

2 Hybrid Open Source PBX for Private / SOHO / SME Public Networks Private Network External Askozia extension (e.g. Home Office) LAN Internet Public ISDN/PSTN WLAN GSM-phone 2

3 Hybrid Open Source PBX for VoIP / ISDN / Analog Easily Configurable Scalable from SOHO to SME From Embedded Hardware up to Server Public Networks Private Network External Askozia extension (e.g. Home Office) LAN Internet Public ISDN/PSTN WLAN GSM-phone 3

4 Features Voic forwarded as attachment and/or retrievable by dialing in with pin Call parking and transfers (blind and attended) Technical less than 12MB firmware images, designed for embedded hardware (e.g. PC Engines, Soekris, Herologic "generic-pc" image runs on any x86 based hardware Telephony Fully supported Video telephony Conference rooms with optional pin multilingual audio-prompt and voic notification s (e.g. nl, en, fr, de, it, jp, ru, es, se, pl) Configuration PHP based webgui configures phone and provider accounts for: SIP, IAX, ISDN and analog Entire system configuration is stored in a single XMLfile searchable database of call detail records 4

5 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 more competent hardware and software extensions 5

6 Background / Timeline Jan project begin Jun first public beta Jul multilingual prompts Sep VoIP over WLAN Sep most common interface types supported Nov extensions system implemented - DID/DDI Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar ISDN provider + phone support Aug Analog provider + phone support Sep Permanent storage system implemented Basis for e.g. - IVR - call recording - music on hold Jan 1.0 released after XX betas Mar 6

7 Midterm Vision AskoziaPBX to become the market-dominant hyprid SoftPBX for Private / SOHO / SME Environments Self-connecting AskoziaPBX VoIP networks throughout the Internet Organize your family and friends 7

8 Target Market Computer System Retailers for example ISP / Telecom Operators for example Hardware Manufacturers for example SOHO Users 8

9 Market Environment Open Source Similar Projects AsteriskNOW, Trixbox, Elastix complete systems with easy to use GUIs AstLinux targets embedded hardware Differences to AskoziaPBX much too large for smaller hardware platforms too much expected of people new to Asterisk & Linux missing a user-friendly GUI Commercial 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 9

10 Standing on the Shoulders of Giants 10

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

12 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 VoIPand Telecom-specialists at IKT 12

13 About IKT / Some Cooperation Partners IKT is an institute associated with the University of Applied Sciences Braunschweig/ Wolfenbüttel; Germany. We are specialized in the research and development of technologies and solutions for IP based communication services, networks and applications. Current R&D activities include technologies such as Voive over IP, Multimedia over IP Session Initiation Protocol (SIP) Open Source Software Packages; Asterisk, SER, FreeSWITCH among others Presence Services IP Multimedia Subsystem (IMS), TISPAN Quality-of-Service-Mechanisms (QoS), IntServ, DiffServ, MPLS Network "VoIP-Readiness IPv6 Protocol conformity tests, particularly TTCN
