Video Infrastructure Update
A deep technical dive into the various integration scenarios available through our expanded
product portfolio on the Infrastructure side. During this session we will bring you up to speed on
the TelePresence server the TIP implementation. We will also dive into what a trunk between
CUCM and VCS will bring to your video and telephony deployments while showcasing best
practices to help you get started. Other topics will cover the strength of combining the Content
server with the Show and Share product for a truly strong corporate streaming strategy. Overall
a deep technical session that aims to deepen your knowledge of our unique infrastructure
proposition.

VCS Overview
The Cisco Telepresence VCS Family

§ VCS Control (VCS-C): video call control and endpoint registration
§ Includes a H.323 Gatekeeper, a SIP Proxy/ Registrar and a H.323-SIP
gateway server
§ Normally deployed within the Enterprise network

§ VCS Expressway (VCS-E): Session Border Controller for SIP/H.323
firewall traversal
§ Registration of traversal-enabled devices
§ Normally deployed outside of the Enterprise firewall or in the DMZ

CUCM CTS Separate CM clusters recommended for TelePresence/Non-TelePresence:
Cluster • CTS endpoints churn code faster and require frequent CM upgrade.
• CM only has 1 video DSCP class per cluster prior to release 8. Cisco
TelePresence SRND recommends a separate class from other video
hence a different CM cluster should be used if there is already video
conferencing in the existing cluster.

Native CTS Mux
Multi-screen Solution for Media

CTS CTS
CTS Mux
• Multi-Screen Systems
• Multiple Audio/Video Channels per Endpoint
• Lack of Multi-Channel Signaling Solution Prior to CTS
Challenge • Each Media Channel Requires Individual Call Setup

• CTS Mux Protocol
• Bundles Multiple Media Channel into 1 Bearer Path (RTP)
• Capability Exchange for Multiple Channels in Same SIP Call
Solution • Identified with RTP CSRC


TIP in Action
TelePresence Interoperability Protocol

TIP Triple Screen Endpoint

• Non CTS Endpoints Has no Knowledge of CTS Mux
• CTS Cannot Interoperate with Other Endpoints
Challenge

• TelePresence Interoperability Protocol
• Derivative of CTS Mux to Negotiate
• Multi-Channel, CABAC, LTRP and GDR Negotiations
Solution
• Cisco Licenses CTS Mux Features as TIP


TelePresence Interoperability Protocol (TIP)
TIP is an open protocol for TelePresence interoperability
•Many video companies have signed the royalty-free TIP license
•TIP Open Source project launched in July
•Cisco to transfer TIP ownership to IMTC

Directional Flow

• Release 2.1 introduced support for CTS
endpoints

• The TS must recognize the incoming call as
a CTS to negotiate TIP successfully

• Currently each CTS must be manually
configured on the TS*

• This flow chart describes the TS matching
behavior

Interoperability and Integration
§ Feature Comparison

1 Future release will add support
2 Only CTS endpoints in call get OBTP, interop devices (non-
CTS) get manual dial-in number
3 This is a CTS only call so Auto-Collaborate is supported
(TIP’s version of BFCP)
4 MXE-5600 is a SIP only device. H.323 endpoints can utilize
MXE by having a CUCM or VCS translate from H.323 to SIP.
