13. Visual Communications Beyond the Boardroom Issues with existing ‘room centric’ implementation: How do I make the video network more accessible ? How do I enable teleworkers to participate in meetings? How can road warriors join a videoconference ? How do I collaborate with partners and suppliers ? How do I effectively share presentations across rooms and PCs? How do I effectively manage PC video users?

14. Existing Solutions for Enterprise Conferencing Use the phone No video Data collaboration optional but no integration to H.239 Use existing H.323 soft endpoints Requires client purchase per user No solution for random partner connection Complex install and maintenance Firewall issues Limited collaboration tools

15. Existing Solutions for Enterprise Conferencing Buy a ‘personal video system’ for key employees Expensive – does not scale Limited data collaboration options No solution for partners Firewall traversal issues

16. Remote Connection Requirements No complex licensing fees No complex installation issues Firewall traversal Data interoperability Streaming for high scalability
