General observations

Delegates from the education and health sectors that attended the summit included UoW, USYD, CSU, LaTrobe, QLD TAFE, Swinburne, Griffith, SA TAFE and AARNet. Tandberg briefly summarised their new products including Experia (Telepresence), Movi (PC video conferencing), HD, SIP, OCS integration, mobility and streaming stressing that a integrated suite of solutions tailored to business needs was important to encourage greater adoption and use.  Photos from day one are available online at http://picasaweb.google.com/aarnetrtc


Serge Sardo (CEO of the Australian Human Resource Institute) discussed "Employee engagement".  He explained the rise of the buyers HR market due to the growth in retirees and low fertility rate.  Employers have to market their job vacancies and promote the organization as employees increasingly want to know what is in it for them.

Increasing the workplace pool is happening through increases in General Skilled Migration; however global migration competition is growing.  Staff turnover is estimated to cost 150% of an employee salary to cover recruitment, induction and lost revenue costs.   Disengaged employees are costing billions of dollars in Australia.  Good HR strategies will keep employees and those that contribute 4 times more to the business need special attention.  To engage them requires a strong purpose and meaning to the job and developing co-worker and manager relationships.  Tackling retention requires measurement and reporting, a range of systems are available.  Organisation's need to build retention costs in their budgets.  Initiatives to retain and engage staff should be identified and implemented.

Sean Lessman (Tandberg) presented on Advanced Applications, SIP and connectivity.  The PSTN system was based on solutions to scale use over time.  H.323 was designed to mimic the PST system, whilst SIP was designed to start over.  SIP is a protocol for setting up and tearing down communications, designed at the same time as H.323 in 1996 based on web protocol concept.  It is not a video or audio protocol, not a firewall traversal protocol, not a collaboration protocol.  SIP extensions (RFC 3261) describe starting and stopping sessions where extensions developed that are unique to specific vendor implementations.  VoIP is moving to SIP, presence would be next as part of the unified communications integration path.  H.323 has scaling issues with gatekeepers and endpoints whilst SIP makes use of DNS in a SIP proxy to connect endpoints together in a more scalable way.  Some best practices have been taken from SIP to H.323 such as URI diallling.  H.323 appears to be going nowhere, SIP will dominate desktop voice, video, web.  Tandberg VCS is designed for SIP to H.323 interworking with Tandberg products supporting both natively and active simultaneously.  There is a 90% feature parity in SIP.  SIP enhancement support cover approx 47 RFCs (from 1889 to 4796).  SIP supports application convergence, mobility, telephony features, next gen telephone network, network intelligence to support new services easier and cheaper endpoints.  SIP enables calls to a person not a location where the call finds me, this saves the hassle on a multi-step process of finding and contacting someone.  SIP enables unified communications. 

Andrew Pillon (Tandberg) talked about VC investment through ease of use. It requires a number of building blocks for success as follows:
    •    A technical architecture/roadmap,
    •    Executive sponsorship (outside the IT department) for visible support and organization wide motivation.  CEOs/CIO need to declare support to the investment and vision. 
    •    Resources need to be in place for marketing (brand awareness, PR), super users (to educate and inspire as liaison between users and IT departments) and technical to make sure what works, works. 
    •    Training is required to build confidence, understanding including positive impacts to staff which increases the adoption curve.
    •    Measurement and monitoring is a constant to review and assess use (adoption curve and ROI)

Dimension data discussed unified communications and how to switch between different levels of communication as opposed to the delivery of a pure rich single solution.  Integration is necessary through middleware and so that people cam communicate and collaborate taking account of operational management and security.  Collaboration would business and IT yields any business benefits, starting that journey will deliver business continuity and resilience capabilities, increased agility of business processes, support for new services and ways to reduce costs through one touch provisioning.

Steve Neville & Will McDonald (Tandberg) discussed the Tandberg bridging products now available as a result of the Codian acquisition, namely the MCU and IPVCR, ISDN gateway (3501) where an ISDN overhaul is underway to support PRIs with hardware for them (4 PRIs) in the box, that can go up to 8 PRIs on the MSE chassis blade, a lot of audio ports.  Codian's IP GW 3500 supports a range of codecs, signalling and media, for example one site has CCM and IP phones, the GW sets up a dial plan to rewrite phone numbers to IP/MAC addresses, this avoids opening up the CCM to the internet.  Another example is where a user dials in, an auto attendant has a list of allowed calls to limit access to only specific conferences.  TMS is integrated with Codian 4500 so that live conferences can be managed by TMS, a new version of the MCU software is required to support an upgraded API.

Sean Lessman (Tandberg) spoke on content streaming with archiving allowing those unable to attend to gain access to improve productivity. The TCS is a network device to create business quality video and multimedia presentations on demand.  TCS supports content from SIP/H.323 sources, most customers were using it to record as opposed to for live streaming.  It can deliver content on Windows Media, Quicktime and Real, with an open API to integrate with existing portals and download support for Zune and iPOD.  TCS can register with Gatekeepers using alias templates to decide what is recorded and who has access.  Administration is achieved centraly with local or MS Active Directory user management for security.  Management can be via TMS or the content server.  TCS supports multicast so long as its on a multicast network. he new 3.0 supports 5 concurrent calls, 2 live.  Off line transcoded output from all recordings.  Video SIP support, H264 and H263 video supported, MPEG 4 media encoding and secure support for AES and DES encyption is supported. Digital Rights Management is not supported today. 3rd party devices can provide content management and monitoring.
