TANDBERG Video Communication Server March 2008

TANDBERG Video Communication Server Background  SIP is the future protocol of video communication and will be a driving force to integrating video communication with the rest of the IP Communication world.  SIP brings advanced capabilities to video not available through H.323. VCS is the center of TANDBERG’s SIP strategy.  FindMe TM brings a new level of personalization and flexibility to video communication and enables telephony like features in video.

TANDBERG Video Communication Server Two base application packages and the FindMe TM option… SIP and H.323 Network Control and Administration Base Package SIP and H.323 Network Firewall Traversal Base Package Call the Person not the Device Option TANDBERG Expressway TM TANDBERG FindMe TM TANDBERG Control VCS deployed with a Control base package is deployed inside the firewall VCS deployed with an Expressway TM base package is deployed outside the firewall Internal SIP & H.323 Devices Public Internet

TANDBERG VCS Control Application Control Base Application Features  Control Base Package  H.323 gatekeeper  SIP controller (proxy registrar)  Deployed inside the LAN  Internal video network control and administration - SIP:H.323 Interworking (transparent dialing/gateway) - Endpoint and Network Infrastructure Registration control - IPv4 to IPv6 Interworking (gateway) - Bandwidth control VCS Control Application H.323 SIP Summary: VCS, when purchased with a Control base package is deployed inside the firewall and functions in a similar capacity to the Gatekeeper. Key difference is that VCS supports SIP and H.323 devices. H.323:SIP Interworking feature parity includes encryption and dual video * ICSA certification is for VCS version X1 *

VCS is the Center of the Video Network VCS IVR Recording ISDN Gateways SD MCU HD MCU TMS UC Server Future Possibilities for interoperability include: INTERNAL ONLY DO NOT DISTRIBUTE Movi* * Movi Firewall Traversal is a future capability

TANDBERG Control Application Control Base Application Key Points  Gatekeeper functionality for SIP and H.323  Migration Path To SIP without having to replace H.323  Integrate video networks and IP Telephony  Seamless SIP – H.323 Interworking

TANDBERG VCS Expressway TM Application Expressway TM Base Application Features  H.323 and SIP Firewall Traversal - Expressway TM, the same standards based Firewall Traversal capabilities in existing TANDBERG Border Controller. - H.323: ITU Standard H & 19 and Assent - SIP: IETF Standard STUN Relay & Discovery - Future functionality with Movi Expressway TM Application VCS, when purchased with an Expressway TM operates in a similar capacity to the Border Controller with additional SIP functionality. * ICSA certification is for VCS version X1 *

TANDBERG VCS Expressway TM Application Expressway TM Base Application Key Points  Standards based Firewall Traversal functionality for SIP and H.323  Migration Path To SIP without having to replace H.323  Seamless SIP – H.323 calls outside the network  PC Based Applications like Movi2 (future capability) will be able to make firewall traversal calls.

Optimal VCS Deployment  The optimal scenario will require at least two VCS boxes (like a Gatekeeper and Border Controller).  FindMe TM application can be deployed both inside and outside the firewall, however it is recommended to be deployed inside the LAN. Control Application Expressway TM Application

VCS Functions with Existing Technology  VCS operates with existing Gatekeepers and Border Controllers on an H.323 basis, so there is no need to swap out existing infrastructure. SIP H.323 Existing Gatekeepers Existing Border Controllers VCS Control Application VCS Expressway TM Application Public Internet SIP & H.323 Public Internet SIP & H.323 Public Internet H.323 Public Internet H.323

Benefits of SIP to Video  Allows different media on the same call (e.g. IM, Voice, Video)  Easy to add features  Extensive Call Forwarding and Hold Capabilities  Works well with other protocols SIP Based Microsoft OCS and other Unified Communication Applications SIP based Voice-over-IP Phones SIP has proven benefits with other forms of communication….

TAA Video Communication Server Option  Call the person, not the device…TANDBERG FindMe TM brings extensive call forwarding capabilities to video communication.  Calls are connected to the appropriate device by dialing only one address. TANDBERG FindMe TM on the road… in her office… at home… in the boardroom…

TANDBERG FindMe TM Application Key Points  Encourages greater use of desktop video  Brings telephony like features to video  Makes it easy to find an individual and to be found  Integrates communication devices making video integral

TANDBERG FindMe TM Application – Case Study #1 Healthcare Application Background: Regional Healthcare system relies on larger hospitals to support smaller hospitals through the use of video. TANDBERG Solution utilizes the combined solution of TANDBERG Codian IP Gateway and the TANDBERG Video Communication Server - FindMe TM Wider and more timely Access to Doctors Across the Healthcare Network Access to more extensive resources for smaller, remote hospitals Access to more extensive resources for smaller, remote hospitals

TANDBERG FindMe TM Application - Case Study #1 Healthcare Application Solution: TANDBERG Codian IP Gateway, along with FindMe TM enables optimal use of hospital resources, including timely access to the right Doctor. VCS FindMe TM 1 – Remote Regional Hospitals use video to call into TANDBERG TANDBERG Codian IP Gateway 4 – Call not answered? Call is routed by FindMe TM to a video operator, who can then forward call to available doctor. 3 – TANDBERG Codian IP Gateway routes call to FindMe TM, which rings which rings all doctors in department…first available doctor answers. 2 – Caller selects appropriate department

TAA Video Communication Server Option  The perfect solution for large enterprise customers with multiple firewalls. Dual Network Interfaces Control Application Expressway TM Application VCS Internal DMZ External DMZ

TAA Video Communication Server Option  Dual Network Interfaces also allows a VCS Expressway to be deployed within the internal-facing DMZ between a firewall and an external-facing router using ACL. Dual Network Interfaces Control Application Expressway TM Application VCS Internal DMZ Router ACL

TAA Video Communication Server Option  Enables security conscious organizations with multi-tiered Firewalls or ACL Border Routers to connect zones within their network. Dual Network Interfaces Key Points  Enables security conscious organizations with proxy non-routable traffic within the DMZ  For Firewall Traversal opportunities TANDBERG advocates standards based firewall traversal mechanisms only, Expressway TM

TAA Video Communication Server Option Awards and Certifications Control and Expressway Applications are ICSA Certified TANDBERG VCS ICSA Certification Report * ICSA certification is for VCS version X1 *

Software Updates VCS Software Update X2  Extended parity between H323 & SIP Encryption supported for H323 – SIP gateway calls. Dual Streams (presentation) for H323 – SIP* gateway calls.  Dual Network Interfaces Allows the VCS Expressway TM to connect to two separate networks in a DMZ deployment.  Easier to manage, quicker to deploy Increased usability of the administration web interface. * Contingent on F7 upgrade to MXP endpoints
