A bit of background

71% of millennial employees show preference for video over audio conferences

Sources: PwC, NextGen Global Generation Study; American Community Survey, UC Census Bureau by globalworkplaceanalytics.com

55% of managers have seen increased demand for videoconferencing

More than 60% of collaboration is done with employees and partners outside the office

Employees in Fortune 1000 companies are not at their desk 50-60% of their time

50-60%

The way we work, and our attitude is changing

By 2019, WebRTC will be utilized for 15% of enterprise voice and video communication, up from less than 1% today.

Between 2015 and 2019, the rate at which organizations will deploy cloud telephony will nearly double, from about 10% to almost 20%.

300%By 2020, over 90% of enterprise voice calls in the digital workplace will originate from collaboration applications, up from less than 30% today.

By 2019, group videoconferencing usage volumes enterprise-wide will increase 400% over current levels, driven by commodity endpoints and cloud-based services.

What Gartner Thinks

There is an explosion in video usage happening, but it is not driven by traditional video conferencing....

Market status – well known fact

Video is for most not yet a company wide

collaboration capability – as little as 5% of all meeting rooms are video equipped –

Why is video not heavily used within the greater user community?

Video is perceived to be complex

Difficult to connect and schedule

Always checking to ensure you see the

content, can you hear me

Shadow IT – users bring in their own

collaboration software

Interoperability headache

Cables are mess/unplugged so

it won’t work

H.323 and SIP

Gateway P2P

Surface Hub

• H323/SIP to MS-SIP translation for signaling

• H264/H263 to H264SVC translation for video

• Converting H239/BFCP content to RDP content

• Transparent for the end user, same as Hub to Skype/Lync

• Dialed URI must route to GW

Where to host the capacity

Transcoding video streams requires "CPU" capacity

The big question is very often:– On-prem

• How much capacity do you need?

– Cloud

• What flavor of cloud?

– Or a combination

• Is that even possible?

Where to host the capacity

On-prem – deployed on internal servers– VMware/HyperV/Xen/KVM

On-prem installation deployed purely on IaaS– Azure/Amazon

Hybrid Cloud– A combination of the above

Private cloud– Dedicated at external provider

Public cloud– Shared at external provider

Enterprise

Dedicated on-premOn internal servers (VMware/HyperV/Xen/KVM)

All media transcoding handled on the enterprise MPLS network

Allows for regional deployment on customer regional data centers

Best quality, managed by enterprise or outsourced mgmt

Optimal for security and flexibility

Some vendors support integration with Skype Conferences on AV-MCU

Surface Hub

VC/Skype GatewayOn prem

Enterprise

Dedicated installationPurely on IaaS cloud (i.e. Azure/Amazon)

Media not on local network, requires good connectivity to IaaS provider

• Azure Express Route

• AWS Direct Connect

Allows for regional deployment on IaaS provider regional data centers

Same as on-prem for security/flexibility and Skype Conferences on AV-MCU

Potentially high cost with dedicated capacity VMs always on + bandwidth

Surface Hub

IaaS provider

VC/Skype Gateway

Enterprise

Dedicated installationHybrid Cloud – combo of onprem and IaaS

On-prem capacity for everyday use (i.e. Vmware/HyperV/Xen/KVM)

Burst to IaaS providers when needed (i.e. Azure/Amazon)

Optimal media path for most calls

Efficient cost spending, and risk reduction with overflow to cloud

Surface Hub

IaaS provider

VC/Skype Gateway

VC/Skype GatewayOn prem

Enterprise

Private cloud

Media handled at provider or on enterprise network (assuming network interconnect)

Good for security and flexibility

Shared management and possibly transcoding, with some dedicated capacity

Can allow for Skype Conferences on AV-MCU with dedicated integreations

Surface Hub

Private Cloud provider

Curstomerdedicated

SP Shared capacity

Enterprise

Public cloud

Shared resources, often at a lower cost, typically VMRs

Less flexibility, normally no or limited gateway offering

URI addressing often uses cloud providers domain name

Meeting formats: VMR, GW and AV-MCUWhat does it mean for the Surface Hub?

Virtual Meeting Rooms– Surface Hub must dial in to VC bridge

Gateway P2P– Dial directly from Hub to video room system

– or to Legacy VC MCU via Interop GW (not recommended)

Gateway AV-MCU / Skype Conference– The native and recommended experience

for a Surface Hub to operate

Virtual Meeting Rooms with Surface Hub

Video MCU

Surface Hub

Dial in to VMR from Hub Same as P2P from Hub to Skype / Lync PIN entry

– No DTMF option (not intended use case)– Embed PIN into dial string if supported

Hub can share whiteboard as RDP to VMR Video show default small User can choose full screen Manual switch if content is

received from VMR This is not the intended

use case for the Surface Hub

– Manual switch if content is received from VMR

Put VC rooms in Exchange – msRTCSIP-PrimaryUserAddress

Gateway AV-MCU / Skype Conference

Easy to schedule

Hub clicks to join on home screen

Hub can share whiteboard as RDP

VC systems can join via gateway

Gateway should support AV-MCU, RDP and Office 365

Surface Hub has data about participants, to send drawings etc

Shows two VC streams on side or side by side in full screen mode

Scheduling of video and Hub meetings

VC centric meetings scheduled in many ways– Some times via VC vendor plugins or 3rd party schedulers

– Simply providing a VMR or endpoint address in mail/calendar

– Requires Skype and Surface Hubs to manually dial

Skype for Business meetings are scheduled in Outlook– Outlook for Windows/Mac/mobile or web

– Skype meetings is the optimal flow for Surface Hub

– Assumes Surface Hub is invited to meeting

Scheduling a Skype meeting in Outlook

How can VC endpoints join Skype meetings?

Depending on vendor support and SfB on-prem vs 365

Dial out from Skype meeting– Drag-and-drop VC room from Skype buddy list

– Add participant in the Hub interface after joining meeting

Dial in to Skype meeting– Dial VC-Skype-GW IVR and enter Conference ID

– Dial Conference ID directly – or add @domain.com

– Click to join via scheduler that reads EWS and automatically connects or prompts on endpoint

Drag-and-drop VC room from Skype buddy list

VC room should be in Skype buddy list (via Exchange)– msRTCSIP-PrimaryUserAddress

Search for it, and add to meeting

Must be invited by a host

Add participant in the Hub interface after joining meeting

VC room should be in Exchange directory– msRTCSIP-PrimaryUserAddress

Search for it, and add to meeting

Dial VC-Skype-GW IVR and enter Conference ID

Normally requires Skype or Lync to be installed on-prem so VC-Skype-GW can look up Conf ID (numeric) and get full URI of the conference– Resolving from: 29905

– To: user@example.com;gruu;opaque=app:conf:focus:id:BP8GAN12

User dials IP/URI of IVR

Use DTMF to enterConference ID

Connecting to meeting

Dial VC-Skype-GW with Conference ID directly

Normally requires Skype or Lync to be installed on-prem so VC-Skype-GW can look up Conf ID (numeric) and get full URI of the conference– Resolving from: 29905

– To: user@example.com;gruu;opaque=app:conf:focus:id:BP8GAN12

User dials Conference IDassuming dial plan allows

Or ie. 29905@domain.com

Dial direct/prefix/domain:• Direct: 29905• With prefix: 5529905 • Domain: 29905@domain.com
