Deploying Skype for Business

Full Hybrid Voice Topology

Pre-requisites: Server Pool

Pool: Lync Server 2013 or Skype for Business 2015 Server Standard or Enterprise Edition

Edge: Lync Server 2013 or Skype for Business Server 2015Mediation: Lync Server 2013 or Skype for Business Server 2015

Co-located or in a separate pool

Tested On-premises PSTN infrastructureActive directory synchronizationSkype for Business “Hybrid Organization” configured

Call Routing Summary

Inbound call flowUser’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.

Outbound call flowUser 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 recordOn-premises server redirects the Skype For Business Online client to the cloud

Amber SfB Online user in

Internet

1. Ricardo places a call to an external PSTN user

2. SIP Traffic routes to SfB Online

3. SfB Online performs RNL of the number

4. Call routed to Edge server (SIP and Media flow via Online Edge first and then via on-premises Edge)

5. If route exists, Edge relays the traffic to Media component in DMZ)

6. Media component sends the traffic to PSTN gateway

• Only PSTN Ingress and Egress from on-premises is enabled with Cloud Connector

Planning & Deployment

Planning• Plan the solution using planning documentation on TechNet• Make sure that all required ports opened in firewalls;• Create external DNS records for Edge pools;• Request external certificate;Deployment• Download and install CloudConnector.msi from download site• For HA, configure Site Directory (Set-CcSiteDirectory• Configure Appliance Directory (Set-CcAplianceDirectory) • Provide Windows 2012R2 ISO• Import Edge certificate to Cloud Connector deployment (Set-

CcExternalCertificateFilePath)• Download Cloud Connector bits (Start-CcDownload; Get-CcDownloadProgress)• Update Cloud Connector Configuration (Export-CcConfigurationSampleFile)• Create VHDX (Convert-CcIsoToVhdx)• Deploy 1st Instance (Install-CcInstance); optional hardware type, -type Normal, Minimal,

Maximal• Configure HA (Register-CcHAInstance, Publish-CcHAInstance)

• In about 2 hours VMs will be deployed;

Connect existing topology to Office 365 using Split Domain & migrate users to Cloud PBX.

Cloud PBX user’s PSTN Traffic transits pool.

Deploy Skype for Business Server and connect it with Office 365.

Customers can operate additional services on-prem (VIS, etc.)

Packaged VMs on Customer Hardware provides PSTN connectivity components with Office 365.

Future offering where partner packages required Skype for Business Server software or VMs with SBC/Gateway

Future offering where PSTN connectivity is bundled with network management and quality of service telemetry for O365.

The Smoothest Road to Cloud PBX is Through CloudBond 365

Deciding which topology is right for you

Your situation Cloud PBX solutionYour PBX system offers unique features that you need to retain. Investigate replacing

your PBX with Skype for Business Server

Your PBX does not offer unique features that you need to retain, PSTN Calling service is available in your region, and you want to use Microsoft-provided PSTN services.

Subscribe to PSTN Calling service

Your PBX does not offer unique features that you need to retain, PSTN Calling service is not available in your region, and you have an existing Lync or Skype for Business Server deployment.

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.

Connect your existing Skype for Business Server deployment with Cloud PBX

Your PBX does not offer unique features that you need to retain, PSTN Calling service in not available in your region, and you do not have an existing Lync or Skype for Business Server deployment.

In this scenario, it is also possible that PSTN Calling service is available in your region, but you cannot consider moving to Microsoft-provided PSTN for other reasons-- such as contractual obligations with your existing carrier.
