Introduction

Overview of VIS

Topology

Deployment considerations

Video teleconferencing device typically used in conference rooms

VTCs in some cases have dual screens: one for video and one for presenting

Some of the expensive VTCs have their own MCUs that can host conferences

Capabilities:Signaling: Cisco/Tandberg VTCs support SIP, H.323Support SDP for media negotiationMedia: Cisco/Tandberg VTCs support RTP/RTCP and the H.264 AVC codec which was standardized in RFC 6184

What is a VTC?

“We are in the process of deploying Skype for Business but we want to leverage our existing investment in our legacy VTCs. How can we connect our VTCs to Skype for Business in the most cost-effective way?”

—Almost every customer

Legacy video teleconferencing systems

New server role both on premises or hybrid with on premises

Aimed at legacy Video Interoperability

VIS is a software solution “built in” to Skype for Business and is scalable

Allowing existing VTCs to connect to Skype for Business, leveraging existing investments

Connectivity to conferences with audio and video as well as peer-to-peer

Simplifies interoperability and eliminates the need for third-party infrastructure

The Skype for Business meeting experience is consistent and familiar to users

Video Interoperability Server (VIS)

SIP trunk modeVTCs remain registered to Cisco infrastructureVideo SIP trunk between CUCM and VISVTCs are Cisco endpoints and can call Skype for BusinessOutbound calls from Skype for Business to CUCM not supported in this initial releaseConferencing functionality:

Signaling

SfB Server

VIS acts as a B2BUA in its interactions with the Signaling Gateway (e.g., CUCM);

It has a Signaling Gateway side and a Skype for Business proxy side

VIS functions like a Mediation Server but for audio and video

On its Signaling Gateway side, VIS implements the necessary SIP interactions to correctly interact with the Video Gateway via a video SIP trunk

On the Skype for Business (proxy) side, VIS acts as a Skype for Business trusted server (much like the Mediation Server) supporting Skype for Business simulcast video

Calls must be initiated from the Signaling Gateway to Skype for Business at this time

VIS sends up to 3 simulcast video streams on its Skype for Business proxy side derived from a single video stream received from the VTC

VIS is deployed in a standalone pool (no co-location)

High level VIS architecture—SIP trunk

Signaling ServerMedia stack

A VIS pool must be standalone (scaled pool—multiple pools)

VIS is the next hop from CUCM

VIS is the media relay where Edge services are a consideration (no bypass for media)

Video Gateways is made dependent on a VIS pool if the VIS pool is configured for SIP trunk registration1:N video SIP trunk support• A particular video gateway can have a single trunk to one and only one VIS pool• A particular VIS pool can interact with multiple video gateways

Topology Considerations

VIS does not transcode the video stream from Cisco VTCs to RT-VideoThe video from a Lync 2010 endpoint cannot be displayed on a VTC (via VIS)The H.264 video from a VTC (via VIS) cannot be displayed on a Lync 2010 endpoint

For conferences and calls involving Cisco VTCs and Lync 2013 or Skype for Business clients, interoperability occurs via H.264 and simulcast supportInteroperability of VIS with Lync 2013 and Skype for Business desktop clients is optimalInteroperability of VIS with non-desktop (Android, iPad, iPhone, Windows Phone, Win8 App etc.) Skype for Business clients tested and supported

VIS — Client Considerations

Cisco VTCs must be running software release TC7.0.0 or above

The set of VTCs that the Skype for Business team has testedCisco C40, Cisco C60, Cisco C90, Cisco MX200, Cisco MX300, Cisco EX60, Cisco EX90, Cisco SX20

Other Cisco VTC models running TC7.0.0 or above may be validated after RTM
