Succeed with #Lync BYOD and WiFi
- 1. Succeed with Lync, BYOD and WiFi Ståle Hansen Lync MVP Chief Technical Architect
- 2. When you do telephony, Lync will become a true productivity tool @StaleHansen
- 3. The Lync 2013 mobile client works on Microsoft, Apple and Android operating systems and is a strong solution for those enterprises seeking a UC and telephony client for their mobile devices. Gartner 2014 Gartner Magic Quadrant for Corporate Telephony 2014 http://www.gartner.com/technology/reprints.do?id=1-23HXCI1&ct=141022&st=sb @StaleHansen
- 4. Clients report poor call quality, dropped calls and system outages in implementations that didn't use a Lync integrator Gartner 2014 Gartner Magic Quadrant for Corporate Telephony 2014 http://www.gartner.com/technology/reprints.do?id=1-23HXCI1&ct=141022&st=sb @StaleHansen
- 5. LAN Wi-Fi Bring Your Own Device (BYOD) Choose Your Own Device Bring Your Own Disaster @StaleHansen
- 6. Users expect good performance in meeting spaces
- 7. Users consume the network in a different way today than yesterday Challenge @StaleHansen
- 8. Salesforce Marketing Cloud – 2014 Mobile Behavior Report http://www.exacttarget.com/sites/exacttarget/files/deliverables/etmc-2014mobilebehaviorreport.pdf
- 9. Goal Help you meet the expectations of mobile users
- 10. Succeed with Lync, BYOD and WiFi • Understand Lync Mobile media flow • Make sure logon is simple • Do unmanaged devices correct • Optimize WiFi for Lync • Evaluate security and authentication @StaleHansen
- 12. KNOW HOW LYNC MOBILE MEDIA FLOW WORKS @StaleHansen
- 13. Lync mobile sign in • Lyncdiscoverinternal.domain.com • Lyncdiscover.domain.com • Lync Mobile is an UCWA application • Will always connect to external web services – Internal UCWA and Externa UCWA attributes is reserved for future use @StaleHansen
- 14. Sign in process @StaleHansen
- 15. Media Path Enterprise Voice @StaleHansen
- 16. Media Path Enterprise Voice @StaleHansen
- 17. Lyncdiscoverinternal and certificates • Lyncdiscoverinternal pointing to Lync Front-End • If internal PKI is used • Unmanaged clients typically don’t trust Root CA • iOS clients will sign in fine • Android clients will give a redirect warning • Windows Phone will not be able to sign in – Use public certificates on Front-End Server – Or point lyncdiscover or lyncdiscoverinternal to external reverse proxy @StaleHansen
- 18. MAKE SURE LOGON IS SIMPLE @StaleHansen
- 19. User name should match mail address NetBIOS sign in is legacy @StaleHansen
- 21. Do it right EXCHANGE WEB SERVICES (EWS) @StaleHansen
- 22. Outlook works perfectly with Exchange Using SCP records to locate autodiscover Lync client is introduced, no exchange integration works THE CHALLENGE, ON-PREMISES @StaleHansen
- 23. Lync use DNS-based discovery method • http://<smtpdomain>/autodiscover/autodiscover.xml • https://<smtpdomain>/autodiscover/autodiscover.xml • http://autodiscover.<smtpdomain>/autodiscover/autodiscover.xml • https://autodiscover.<smtpdomain>/autodiscover/autodiscover.xml • _autodiscover._tcp.<smtpdomain> @StaleHansen
- 24. MAPI fallback when EWS fails • Exchange delegation information (MAPI only) • Missed Conversations history and Call Logs are written – Retrieving conversation history fails • Voice Mail count only • Exchange integrated Archiving will work Major failures • Presence update based on calendar • Presence based on Out of Office messages • All mobile clients fail to connect to Exchange @StaleHansen
- 25. Features available only with EWS • Unified Contact Store • High-Resolution Photos • Meeting tab • Contact Information • Presence based on Calendar Information • Conversation History – Missed Conversations – Missed Calls • Voice Mail Playback @StaleHansen
- 26. That is why we Lync folk care about Exchange Web Services @StaleHansen
- 27. Best Practice publishing EWS • DNS A Record for autodiscover.domain.com – SRV is supported, but not recommended – Multidomain? Use HTTP redirect • Publish using NTLM, no pre-authentication – EWS and autodiscover – Avoids authentication pop-up for EWS • No need to Set-AutodiscoverVirtualDirectory – Should point to HLB with correct autodiscover certificate @StaleHansen
- 28. DO UNMANAGED DEVICES CORRECT @StaleHansen
- 29. access and placement @StaleHansen
- 30. @StaleHansen
- 32. Clearpass onboarding and network authentication @StaleHansen
- 33. 1. 2. 1. 3. 4. 5. 6. 7. 8.
- 34. OPTIMIZE WIFI FOR LYNC @StaleHansen
- 35. access vs quality @StaleHansen
- 36. WiFi • Signal Strength • Lync quality performance
- 37. WiFi problem areas • Shared medium • Limited band selection in 2.4 GHz band • Was designed for none-real time data usage • Deployed for access, not throughput @StaleHansen
- 38. How to optimize for voice over WiFi • WiFi tag Lync voice traffic with DSCP value – Through heuristic approach, deep packet inspection and guestimates – Use QoS to prioritize Lync voice traffic – Great for unmanaged devices • Move to 802.11n and 5ghz or 802.11ac • High-density AP deployments – Closer to users • Fast inter-AP handover support – All venderos stress end to end optimization – Endpoint -> WiFi -> LAN -> WAN -> LAN -> WiFi -> Endpoint @StaleHansen
- 39. End to end optimization @StaleHansen
- 40. No handover from WiFi to cellular @StaleHansen
- 41. Validate your WiFi network with Ixia • Discovery Phase – Understand what network environment exists – Understand user modalities • Modeling Phase – Determine Lync utilization per AP • Traffic Simulation – Using a Lync Traffic simulator, connect clients and apply real traffic to production network and monitor factors that affect the quality of Lync traffic: delay, jitter, and packet loss • Report – Analyze factors affecting quality and produce a full report with recommendations @StaleHansen
- 42. Validate your network • Network Stats (RSSI, PHY) – Target & other networks – HTTP speed test • Lync results per location – By traffic class (voice, video) – By client
- 43. EVALUATE SECURITY AND AUTHENTICATION @StaleHansen
- 44. Pre-authorization in DMZ Lync is not built in that manner today @StaleHansen
- 45. Challenges • Lync clients need to authenticate directly • Native passive authentication breaks exchange @StaleHansen
- 46. Passive authentication • Supported on WP8 and iOS • Works only with Lync, breaks Exchange Web Services – Meetings environment – Voice Mail environment – UCS will still work through the Lync Server @StaleHansen
- 47. • A number of third parties can sit in the HTTP flow/Reverse Proxy Role and add additional Security – Restrict sign in to selected devices – Authenticate specific devices to specific users – Use dedicated “lync mobile” credentials so that AD credentials to not sit on the phone • Vendors include – PointSharp – Lync Solutions – LyncShield @StaleHansen
- 48. PointSharp • Lync reverse proxy • App specific password • Device control • User identity • Pre-authentication • 2-factor auth @StaleHansen
- 49. Media Lync Web Services PointSharp Web Services Exchange Web Services
- 54. Goal Help you meet the expectations of mobile users
- 55. OPTIMIZE WIFI FOR LYNC AND UNMANAGED DEVICES @StaleHansen Want happy users?
- 57. Thank you! Remember to evaluate the sessions @StaleHansen
Editor's Notes
- #7: Image is taken by Ståle Hansen (the speaker)
- #25: Retrieving conversation history fails Exchange 2013 UCS fails No High-Resolution photos
- #50: http://www.lyncexch.co.uk/mobile-security-with-pointsharp/
- #53: In the first half of 2015, the next version of Lync will become Skype for Business with a new client experience, new server release, and updates to the service in Office 365. With the best of Lync, and the best of Skype, we believe that Skype for Business will again transform the way people communicate by giving organizations reach to hundreds of millions of Skype users outside the walls of their business.
