Pexip and Skype for Business
Interoperability & Integration
23 Mar 2017

Challenges
Three key technologies do
not work well together:
Skype for Business,
traditional video
conferencing, and WebRTC
Traditional conferencing
infrastructure is based on
custom hardware. It is very
expensive, and complex to
operate.
Enterprise technologies lack
scale to provide all
employees with virtual
meeting rooms for voice,
video and data
Interoperability Cost & Complexity Scalability
Challenges faced by enterprises using video collaboration
Datacenters and
virtualization is the norm.
Move to cloud has started.
Collaboration infra-
structure lags behind.

Gartner:
In 2019 WebRTC will power 15% of

400% over current levels

Pexip Makes These Technologies Work
Together at Scale
On-premise Deployment
Pexip Infinity can be deployed in the cloud, on premises or both
Pexip Infinity makes all these technologies interoperate at scale
A deployment may consist of 1 or 100 servers, and can handle hundreds of thousands of users

Pexip Infinity Key Functionality
Distributed Conferencing
Voice, video and data conferencing allowing any
mix of participants in the same meeting – SIP,
H.323, Lync, Skype, Web, Mobile, VoIP
Distributed Gateway
Any-to-any gateway allowing any endpoint (e.g.
Lync, Skype, Web) to call any other endpoint
directly
Distributed Call Control
Multiprotocol SIP/H.323/WebRTC registrar,
enabling advanced call processing scenarios.
Simplifies deployment
Distributed Edge
Provides policing of the enterprise edge, with
simplified edge design compared to existing
solutions. Coming in 2016.

Pexip Infinity Distributed Architecture
Scale
Distributed architecture – multiple VMs connected
across locations. Increase capacity while running by
adding VMs, locations. Active deployments with over
100,000 VMRs configured
Cost
Easier to deploy and manage than any competing
enterprise architecture. Single portal to manage all
VMs, even for global deployments. Saves bandwidth
across the WAN.
Resilience
Within a datacenter, fail over from one server to
another. Between datacenters – location failover.
Resilient to temporary network splits.
Cloud
Deploy on standard servers on premise. Deploy in
Azure or Amazon or other IaaS. On-premises for daily
needs, burst to cloud for more capacity.
$
Bandwidth savings
between locations
Burst to cloud in one
or more locations
Very low latency between

Distributed Deployment in Azure
Pexip Infinity Distributed Architecture is perfectly
suited for deployment in Azure:
Small VM for Management Node
Larger instances for Conferencing Nodes
Place Conferencing Nodes in relevant regions
Connect Conferencing Nodes w/Azure Site-to-Site VPN
The entire Pexip deployment, consisting of dozens of
VMs, still behaves like a single entity
All Conferencing Nodes are automatically discovered by
and provisioned by the single Management Node
Conferencing Nodes can be added and removed on the
fly, without downtime
Azure Site-to-Site VPN

Conferencing Nodes

Capacity for everyday usage on-prem
Capacity for excess usage in the cloud

Enterprises ARE moving workloads to cloud
24/7 cloud VMs are expensive: 3-5X hardware cost
Cloud bursting: Only a few servers need be always o

Hybrid: Bursting into Azure Cloud
• Automatic bursting to Amazon since V13
o Includes starting/stopping instances on demand
o Why? Reduces cost dramatically
• Deploying Pexip in Azure works already
o Customers have been using this a while
• Adding automatic bursting to Azure
o Start/stop Azure instances automatically
o Will work exactly the same as Amazon AWS

Deploying Skype for Business

Call Routing Summary
User’s Direct Inward Dial (DID) number terminates at PSTN gateway or PBX.
Call is routed to on-premises Skype For Business deployment.
User’s Active Directory object indicates a different deployment locator.
Request is proxied through on-premises Edge proxy to Skype For Business Online.
Invite is routed to end user’s logged-in endpoints.
If accepted, media is routed either locally or through the company’s Edge Server or firewall.
If rejected, media is routed to Cloud PBX Voice Mail.
User instantiates a PSTN call.
Client normalizes number and sends invite to home server.
Voice policy enforcement and call authorization is performed on-premises.
Call is routed to PSTN via Mediation Server.

Registration – Online User
Skype For Business Online client
discovers the server through the Domain
Name Service (DNS) Service Location
(SRV) resource record
On-premises server redirects the Skype

Incoming PSTN Call
An incoming PSTN call is routed to the on-

The number is located via Reverse Number
Lookup (RNL), routed to Skype For Business
Online, and then routed to the Skype For
Business Online endpoint

Deciding which topology is right for you
Your situation Cloud PBX solution
Your PBX system offers unique features that you need
to retain.
Investigate replacing
your PBX with Skype

region, and you want to use Microsoft-provided PSTN
services.
Subscribe to PSTN

your region, and you have an existing Lync or Skype

In this scenario it is also possible that all your users
are in the United States, but you cannot consider
moving to Microsoft-provided PSTN for other reasons-
- such as contractual obligations with your existing
carrier.
