11. Managing Voice Users - Group Policy Policies override server settings Telephony mode: 0 = Enable computer-to-computer calling only. Call control is not enabled (default). 1 = Enable Enterprise Voice telephony features. 2 = Enable RCC and computer-to-computer calling. 3 = Enable both Enterprise Voice and RCC. 4 = Enable RCC without computer-to-computer calling. 5 = IM and Presence only, no audio Location Profile Other key policies: SIPSecurity, Encryption Import template into Group Policy MMC snap-in

12. Provisioning users

13. Authorisation/Routing/Dialling Four building blocks Location profiles Collections of Normalisation Rules Voice policies Contain Phone Usages Routes Associated with Phone Usages This session doesn’t cover planning or theory Attend UNC305 to learn about that

14. Easiest approach for administration Use the Enterprise Voice Route Helper Tool offers multiple features Configuration Ad-hoc testing Ability to run test cases Ability to avoid certain ‘career issues’ Can be done manually, but why would you?

16. Enterprise Voice Route Helper

18. Why is monitoring so important? Because we all want to stay employed OCS is a distributed system There are many environmental dependencies New ‘software’ model brings new challenges Users may be more sensitive than usual

19. Which tools can help me? OCS 2007 R2 Monitoring Server (QoE) OCS 2007 Deployment Verification Tool Agents Answering agent VoIP Test Set Pre-call Network Diagnostic Tool

21. Quality of Experience Considers all factors influencing user perception, such as: Hardware Application Psychological Physical parameters Media stack monitoring and optimizing in real-time Intelligent end points Inferior UC devices can cause disproportionate problems QoE is about network AND payload content

22. Quality of Experience Summary Right-provision networks Use DiffServ / SLA where appropriate Intelligent endpoints adapt to network conditions Use OCS 2007 & OCS 2007 R2 logo devices QoE focuses on the network and payload Monitoring Server aggregates QoE data

23. Monitoring Server: Collection Integrated component of OCS 2007 R2 Receives a ‘QoE’ CDR after every voice call Each CDR contains important quality metrics Reports come from endpoints and servers All reports are stored in a database

24. What might you use QoE Data for ? Helpdesk troubleshooting Network engineering Nearly real-time monitoring Early warnings Validation of plans Future planning And many more uses...

25. QoE Architecture Client (UC endpoint) Mediation Server Systems Center Operations Manager (alerts) SIP – PSTN Gateway Client (PSTN endpoint) Leg A Leg BLeg C Monitoring Server MSMQ QoE Service QoE DB QoE Agent MSMQ Front End Server SQL Server Reporting Services In this example, QoE reports generated for legs ‘A’ and ‘B’ only

26. Monitoring Server: Useful data Information is grouped in a logical manner Location (one or more subnets) A/V Conferencing Server Mediation Server Out of box reports ready to use Scenario (PC-PC, PC-PSTN) Summary Trends By specific user And more...

27. Monitoring Server: Early warnings Rich data stored in database is actionable Data is ready for consumption by SCOM Fix problems before many users feel pain This can also show up ‘subtle’ voice issues

28. Key Metrics Per Call SIP Session Data: Endpoint IP address/mask Inside/outside user flag ICE Connectivity Path Codec(s) Network connectivity information Wired vs. WiFi Link speed VPN or not Capture/Render Device Noise Level/Signal Level Echo metrics for the client Speech/signal and noise metrics for the client

29. Key Metrics Per Call continued Network Packets/Packet Loss Rate Jitter/Round Trip Time Latency Burst PSTN Mediation Server to gateway leg reporting Video Quality Metrics Conversational MOS Listening MOS Sending MOS Network MOS/Network MOS Degradation

30. Voice Quality Test Options Subjective: Uses panel of testers to determine VoIP quality Results vary from one test to another Active: Inject reference signal into stream and compare it to the output at other end Objective: QoE Server approach Similar to ITU ‘PESQ’ Passive: Output signal is compared to a model to predict perceived quality

31. Absolute Categorization Rating (ACR) Traditional Assessment of Voice Quality Subjective test of Voice quality based on a scale of 1–5 Scoring is done by group of testers listening to calls Listeners rate the calls Mean Opinion Score (MOS) is the average ACR RatingQualityImpairment 5 ExcellentImperceptible 4 GoodPerceptible but not annoying 3 FairSlightly Annoying 2 PoorAnnoying 1 BadVery Annoying

32. Be careful when interpreting data All MOS scores are not created equal It’s important to understand OCS MOS usage: OCS MOS scores useful to compare with OCS Not useful for comparing with other systems The important thing is quality in YOUR deployment

33. QoE Reporting - Mean Opinion Score (MOS) Wideband vs. Narrowband MOS Listening, Sending, Network MOS on wideband scale Conversational MOS on narrowband Be aware of scale when comparing vendor-vendor scores For MOS, need to compare similar scenarios Larger sample sizes deliver more meaningful average scores Minimum of 30 calls Just comparing MOS values may be meaningless Average of scores collected during “subjective” test

34. MOS Detail Network MOS: Considers only network factors Useful for identifying network conditions impacting quality Supported by all UC endpoints, except Exchange 2007 UM Listening MOS: Considers many factors including: Codec used Capture device characteristics Transcoding, mixing, defects from packet loss/packet loss concealment, speech level, and background noise Useful for identifying payload effects impacting quality Supported by Communicator 2007

35. QoE Reporting: Two Classes of MOS Scores Listening Quality MOS (MOS-LQ): Commonly used class of MOS scores for VoIP deployments Does not consider bi-directional effects, such as delay/echo Microsoft UC provides three wideband MOS-LQ metrics: Network MOS: Audio played to user Listening MOS: Audio played to user Sending MOS: Audio sent from user Conversational Quality MOS (MOS-CQ): Considers Listening Quality & bi-directional effects Microsoft UC provides one narrowband MOS-CQ score Conversational MOS: Audio played to user

36. Max MOS Rating by Codec Network MOS scores vary considerably, based on call type Call type determines codec used Different codecs have different max MOS ratings for Network Look carefully at MOS score and scenario ScenarioCodecMax Network MOS PC – PC Call RTAudio WB4.10 Conference Call SIREN3.72 PC – PSTN Call RTAudio NB2.95 PC – PSTN Call SIREN3.72

37. Deployment Changes for OCS 2007 R2 OCS 2007 “Archiving & CDR” Server Role QoE Server available out-of-band OCS 2007 R2 Archiving server role Monitoring server role = QoE + CDR

38. Basic Topology Options Everything can be collocated with SE server! Clearly not recommended for large deployments Requires full version of SQL Server Monitoring and archiving roles can be collocated Databases can be clustered Each role can be collocated with its database Databases can be collocated with the BE database SE: Standard Edition BE: Back-end

39. Pool Association Options Pools associated to one monitoring server Mediation servers associated to one monitoring server Monitoring servers can support multiple pools

40. Monitoring Server Database Capacity Planning Database size is dependent on call volume and call report retention settings Each day’s call report uses approximately 16.8 kilobytes (KB) of database storage per user Estimate database size with this formula: Example; using the default call report retention time for 50,000 users: DB size = (DB growth per user per day)*( # of users)*(# of days) DB size = (16.8 KB/day)*(50,000 Users)*(60 days)= 50.4 GB Values in this example are based on the capacity planning user model from the OCS 2007 R2 documentation.

41. Configuration steps Install Message Queueing Install SQL Server and reporting services Install and activate monitoring server Deploy reports Install management pack (optional) Configure logging Associate pool/servers with monitoring server Ensure port 5069 is open on load balancer Start service Note: Not all steps may be required if IM archiving is configured.
