Why Do These Problems Persist?
Multiple Protocols
- Network protocols: PSTN (H.320), IP (H.323, SIP, MEGACO, MGCP)
- Management protocols: SNMP, RS232, HTTP, etc.
- ISDN to IP transition, IP Convergence
Multiple Vendors
- Multiple vendors for endpoints, bridges, gateways, gatekeepers
- Most organizations have 3 or 4 different brands in their environment

No Tool to Unite the Environment
- Video Conference Schedulers - limited to scheduling
- Device Utilities - device-centric, proprietary
- Network Managers - no video support
