Creating a Unified TelePresence Solution
Unified TelePresence Solution SIP and TIP What is TIP? TelePresence Interoperability Protocol (TIP) evolved from a protocol Cisco designed and created to overcome challenges faced in multiscreen/multichannel TelePresence environments. Is TIP proprietary? Cisco created, then transferred,tip to the IMTC (International Multimedia Teleconferencing Consortium) to license royaltyfree. Today several third party vendors have implemented TIP on their endpoints and infrastructure. What is the relationship between SIP and TIP? H.323 MGCPSIP SCCP ISDN TIP TIP relies on an initial call negotiation using SIP. SIP is responsible for negotiating the RTP and RTCP IP addresses and ports. These RTP/RTCP channels are used not just for media, but also for the TIP signaling messages. TIP will take over after SIP and re-negotiate things like the number of video and audio streams, multiplexing of multiple media streams, etc. SIP Invite SIP Trying, Ringing, 200 OK RTP/RTCP negotiated by this point via SIP SDP TIP negotiation TIP is used in conjunction with SIP
Creating a Unified TelePresence Solution Unifying call control, scheduling, and management CUCM VCS Challenge: CTS endpoints use Cisco Unified Communications Manager (CUCM) for registration, call routing, etc. EX/MX/C series endpoints use Cisco Video Communications Server (VCS). Solution: Integrate call control clusters via SIP trunk. Also add support for EX/MX/C series endpoints to register to CUCM directly. Still use VCS for B2B communications and firewall traversal, as well as advanced video functions. Challenge: CTS endpoints used Cisco TelePresence System Manager (CTS-Man) to integrate with calendaring applications and schedule multipoint resources. SX/EX/MX/C series used the TelePresence Management Suite (TMS), not only to schedule, but also manage and provision endpoints and multipoint resources. Solution: Add support for CTS-Manager to manage/schedule the TelePresence Server and SX/EX/MX/C series endpoints. Add support for CTS endpoints to be managed/scheduled by TMS. Also add OBTP support on TMS. SIP H.323

Call Control
Call Control CUCM Software-based call processing system built on Linux Started as a video PBX in 1997 Supports 30,000 endpoints in a cluster Runs on Cisco MCS and UCS servers Uses a variety of voice and video protocols including SCCP, SIP, H.323, and MGCP
Call Control VCS Designed specifically for video deployments Two types: VCS Control VCS Expressway Supports 2500 registrations on single VCS, 10,000 in a cluster
Call Control Connecting CUCM and VCS Clusters CUCM SIP Trunk connects to VCS Neighbor Zone SIP trunk connects CUCM call control with VCS call control H.323, SCCP, MGCP translated to SIP before being sent to other call control cluster Encryption supported (some dependence on where endpoints are registered) Some of the recent CUCM features which help functionality of SIP connection to VCS include: Replace IP address with Organizational Top Level Domain in call signaling Support of 80-bit authentication tag for encryption in addition to 32-bit CUCM Cluster VCS Cluster EX90 SIP 3 rd Party H.323 CTS 3010 MXP SIP H.323

Conferencing Transcoding vs. Switching Transcoding Active Presence Ability for different bandwidth speeds/resolutions Custom layouts Size of meetings is limited by DSP hardware Higher cost per port MCU TelePresence Server Switching Extremely low latency (<10ms) Ability to scale higher Low cost per port Can be virtualized Limited to basic full-screen video switching (No Active Presence) All endpoints must support and agree on single resolution/frame rate Interoperability requires additional hardware (transcoding) CTMS
Conferencing Types of conferences Ad hoc Conference Impromptu meetings, they are not scheduled beforehand,nor require an administrator to initiate them. Suitable for smaller, on-the-fly, meetings. A point-to-point call escalated to a multipoint call is considered ad hoc. Rendezvous Conference Also called meet-me/permanent/static conferences, requires endpoints to dial in to a pre-determined number. Often used for recurring meetings which involve different endpoints each time. Scheduled Conference Provides a guarantee that endpoints and multipoint resources will be available at a certain time. Endpoints join manually or are automatically connected by the multipoint resource.
