Call Flows
New ConceptsContact Object Based Routing Provides static routing of phone numbers to destinations such as applications An AD contact object is created for each access number with the following information: SIP AOR (Address of Record) Phone number (For RNL) Display phone numberAssociated poolApplication typeApplication destination (GRUU)
New ConceptsTrusted Conferencing Identities OCS allows applications join a conferencing with trusted conferencing identities (services) Trusted conferencing services can send requests to conference without getting challenged A GRUU is associated with each trusted conferencing service, so OCS can route a request to the application’s listening port Trusted conferencing services can: Impersonate a conferencing user (i.e. CA)Act as a “trusted bot” (i.e. CAS)

Reporting and Monitoring
Conference DirectoryWhat is it? A mapping of to Conference IDs to Conference URIs Why do we need it? It is necessary to convert SIP URIs to numeric only ids input from numeric entry systems (such as PSTN) What is its impact? No end user impact Admins need to maintain Conference Directories (Disaster Recovery, Decommissioning Pools, Moving Pools)Related TermsDirectory ID: a short numeric ID used to identify a conference directoryConference Resolution: Process of mapping a conf ID to a conference URI
Reporting and CDRMain data points captured for conferences Conference URI Conference start time Conference end time User join timeUser leave time User join time to conferencing servers (A/V, Data, IM etc)User leave time from conferencing serversJoin via PSTN (For A/V Conferences only)
Reports can be filtered by: Dates ( Admins can choose the range) Granularity (Hourly, daily, weekly, monthly) Participant Count/ Conference Count/ Minutes Monitoring Server Reports
Performance Counters in SCOMSome key Performance Counters collected by the OCS Management PackIncomplete Calls per sec, Total Incomplete calls Total calls successfully transferred to conference Current & Total # of Calls on Music on Hold ( MoH ), Calls Timed out on MoH Total Calls from UC ClientTotal # of Mute/Un-Mute/Entry/Exit announcementsCurrent & Total # of attendees that have joined conferences, Current & Total # of active personal announcersCurrent & Total # of conference attendeesPerformance Counters hold data since the last restart of OCS 2007 R2
Capacity and Scalability Component Supported Performance Conferencing Attendant 450 simultaneous calls (based on a computer with 8 processor cores running at 2.33Ghz, and 4GB of memory) Collocated Access Edge & Web Conferencing Edge Server Access Edge Server: 5,000 client connections Web Conferencing Edge Server: 1,500 client connections Collocated Access Edge, Web Conferencing Edge and A/V Edge Servers (Consolidated Edge Topology) Access Edge Server: 5,000 client connections Web Conferencing Edge Server: 1,000 client connections A/V Edge Server 500 concurrent audio/video sessions
