Telepresence Interop Challenges- Features
Lack of an open Interoperability standard across multiple vendors.
All equipment use SIP, H323 and H.264 however there are proprietary elements that prevent smooth Interop.
No Interop solution without using additional equipment to trans-code that adds delay and quality issues
All feature parity not available even with trans-coding equipment:
Encryption
Presentation/data sharing capabilities
Multi-Screen Support
Single button dialing & Audio/video add in.

Network fault tolerance very low
Strict policing at L2 devices
Higher Jitter and Delay to span geographic distances
High Out of sequence packets and low buffers in the MCUs.
Lack of a central registration point for service providers.
NAT non-compliance (H323) prevents extended reach.
IPV6 support
