How System Configuration Affects Route Patterns

Before planning for installation, you should understand how configuration of the Cisco Unified Conferencing for TelePresence system components identified in Table 1-2 affects route patterns.

Table 1-2 System Component Configuration and Route Patterns

Component	Description	Reference
Cisco Unified Videoconferencing 3500 MCU
Services configuration	During services configuration, you define the type of meeting that you want to provide to end users and identify the service by assigning it a service prefix. The service prefix becomes part of the meeting ID, and the meeting ID is used by the Cisco Unified Communications Manager to route incoming calls to the MCU. Service prefixes must be unique and cannot conflict with or contain another service prefix. For example, if service prefix 123 is defined, there can be no service prefix 1 or 12 because they can result in digits that match 123. Similarly, if the service prefix 1 is defined, there can be no service prefix 12 or 123. Example 1 Your company uses five-digit dialing for internal calls, and you want to designate all calls that begin with 3 as calls for Cisco Unified Conferencing for TelePresence meetings. Configure a service with service prefix 3. Example 2 Your company uses five-digit dialing for internal calls. You want to designate specific calls that begin with 3 as calls for Cisco Unified Conferencing for TelePresence meetings, and you want to define services by switching type. Configure a service for site switching with a service prefix of 37, and configure a service for segment switching with a service prefix of 38.	See the "Creating New Services" section in the Configuration Guide for Cisco Unified Videoconferencing 3500 MCU Release 5.2.1.
Cisco Unified Conferencing for TelePresence
Meeting ID length configuration	To identify the service that will be provided for a meeting, Cisco Unified Conferencing for TelePresence generates a meeting ID by prepending the service prefix to a random number, the length of which is determined by the configured meeting ID length. Therefore, the number of digits you configure for the service prefix affects the resulting number of digits in a generated meeting ID, which is the phone number end-users dial to access the Cisco Unified Conferencing for TelePresence meeting. Example 1 (continued) The MCU prepends service prefix 3 to the default, four-digit meeting ID length, resulting in a five-digit meeting ID. Configure the route pattern in Cisco Unified Communications Manager as 3.XXXX so that all calls beginning with 3 are routed to the MCU, and callers are placed directly into a meeting with the defined capabilities for that service. Example 2 (continued) Because the MCU prepends service prefixes 37 and 38 to the default, four-digit meeting ID length, resulting in a six-digit meeting ID, configure the meeting ID length as three, and configure the route patterns as 37.XXXX for site and 38.XXXX for segment.	See the "Configuring Meeting ID Settings" section in the Configuration Guide for Cisco Unified Conferencing for TelePresence Version 1.1.

How System Configuration Determines Video Quality and Affects End Users

Before planning for installation, you should understand how video quality is determined by the settings you configure on the Cisco Unified Conferencing for TelePresence system components that are identified in Table 1-3 and how these settings affect end-users.

Table 1-3 System Component Configuration and Video Quality

Component	Description	Reference
Cisco Unified Communications Manager
Region configuration	You must allocate enough bandwidth to regions that include Cisco TelePresence devices. The video call bandwidth specified in Cisco Unified Communications Manager region configuration takes effect when the bandwidth requested exceeds the region, affecting calls by end users as follows: •If the bandwidth changes such that the quality of the resolution is not affected, for example from 4Mbps to 3Mbps, the call continues to the MCU at 3Mbps. •If bandwidth changes such that the quality of the resolution is affected, for example 4Mbps to 2Mbps or from 1080p to 720p, the call is not successful.	See the documentation for your Cisco Unified Communications Manager release.
Device configuration	Cisco Unified Communications Manager supports six quality settings for Cisco TelePresence devices, ranging from 1Mbps 720p to 4Mbps 1080p per display. Cisco Unified Conferencing for TelePresence chooses the service to provide to end users based on the lowest quality setting of all invited Cisco TelePresence devices.	See the Cisco Unified Communications Manager Installation Guide for the Cisco TelePresence System for your release.
Cisco Unified Videoconferencing 3500 MCU
Services configuration	You must create a service that specifies the maximum call rate and switching type for each type of service that you want to provide to end users. •When end users schedule meetings, Cisco Unified Conferencing for TelePresence chooses the service that most closely matches but does not exceed the lowest quality setting of invited Cisco TelePresence endpoints. The switching type, however, must match exactly; otherwise, meeting scheduling fails. For example, if an end user schedules a site-switched meeting with a mix of 720p and 1080p endpoints, but there is no 720p, site-switched service defined on the MCU, meeting scheduling fails. •When end users dial in to meetings, the MCU provides the service defined for the service prefix that the end user dials. If the quality of calls by end users meets or exceeds that of the service, the call continues with audio and video. If the quality does not meet that of the service, the call continues with audio only. Tip If all the endpoints in your environment have the same quality setting, you need only to configure one service for site switched and one service for segment switched to support that quality setting.	See the "Creating New Services" section in the Configuration Guide for Cisco Unified Videoconferencing 3500 MCU Release 5.2.1.
Cisco Unified Conferencing for TelePresence
System usage configuration	The Cisco Unified Conferencing for TelePresence quality settings correspond directly to the quality settings in Cisco Unified Communications Manager. For example, the Cisco Unified Conferencing for TelePresence setting Highest Detail, Best Motion corresponds to the Cisco Unified Communications Manager quality setting Highest Detail, Best Motion: 4Mbps 1080p per display. The default quality setting takes effect when end users do not invite Cisco TelePresence devices to Cisco Unified Conferencing for TelePresence meetings.	See the "Configuring the Video Quality and Switching Mode" section in the Configuration Guide for Cisco Unified Conferencing for TelePresence Version 1.1.

About Meeting Scheduling Options

Cisco Unified Conferencing for TelePresence supports scheduling meetings through Microsoft Outlook, on the web through an end-user interface on the Cisco Unified Conferencing for TelePresence server, or a combination of both, though system behavior for modifying and deleting meetings is unique for each option.

For information about the required configuration to implement scheduling options, see the following sections:

•Completing the System Preparation Checklist for Microsoft Outlook Scheduling, page 2-2

•Completing the System Preparation Checklist for Web Scheduling, page 2-3

For information about scheduling meetings, see the User Guide for Cisco Unified Conferencing for TelePresence Version 1.1 or the Quick Start Guide for Microsoft Outlook Integrated with Cisco Unified Conferencing for TelePresence Version 1.1.

About User Profile Management Options

Cisco Unified Conferencing for TelePresence supports automatic, manual creation of user profiles, or a combination of both.

The system automatically creates a user profile when a new user attempts to log in to Cisco Unified Conferencing for TelePresence and is successfully authenticated by Cisco Unified Communications Manager. This method allows eligible, unprofiled users to use Cisco Unified Conferencing for TelePresence without waiting for a system administrator to create their user profiles.

These end users have access to their end user profiles via the web; however, they continue to be authenticated by and log in with their Cisco Unified Communications Manager credentials. Names of end users who have not logged in to Cisco Unified Conferencing for TelePresence do not display in the list of meeting invitees in the web scheduling form.

Alternately, you can manually create end user profiles on the Cisco Unified Conferencing for TelePresence server. Manually creating user profiles is useful for adding a few new users to the database to restrict access, for example. These end users have access to their end user profiles via the web and can change their associated passwords.

System Configuration Example

Company A uses five-digit dialing for internal calls. The administrator designates calls that begin with digits 36 - 39 as calls for Cisco Unified Conferencing for TelePresence meetings and defines services by switching type.

Based on the configuration for Company A described in Table 1-4, Figure 1-1 shows how system components work together to provide Cisco Unified Conferencing for TelePresence meetings.

Figure 1-1 Cisco Unified Conferencing for TelePresence System

1	An end-user logs in with an existing Cisco Unified Conferencing for TelePresence user profile and schedules a site-switched meeting, including Conf_room1, Conf_room2, and Conf_room3 either by using the web interface or the Microsoft Outlook plug-in.	6	At meeting time, Cisco Unified Conferencing for TelePresence contacts the MCU to create the meeting.
2	The Cisco Unified Conferencing for TelePresence server receives the meeting request, verifies that resources are available on the MCU for the given date and time, and chooses the meeting type with service prefix 37 because the Cisco TelePresence device associated with Conf_room1 has the lowest quality setting, generating meeting ID and phone number 37nnn.	7	The end user obtains meeting details from either the Outlook calendar event, the e-mail meeting notification, or by logging in to the web interface and dials in directly to the meeting by using the meeting ID number 37nnn.
3	Cisco Unified Conferencing for TelePresence puts meeting details into the e-mail notification template and sends the notification either to the Outlook client of the end user or directly to invitees via the SMTP server.	8	Cisco Unified Communications Manager receives the call, matches the digits to the 37.XXX route pattern, and sends call to the MCU that is configured as a SIP trunk device and designated the gateway for this route pattern.
4	Microsoft Outlook only: The Outlook client schedules the meeting on the calendar of the end user and sends the meeting notification to the Exchange server.	9	The MCU receives the call and hosts the Cisco Unified Conferencing for TelePresence meeting, providing the qualities and capabilities that were defined for the service with service prefix 37.
5	Microsoft Outlook only: The Exchange server sends out the meeting notifications to all meeting attendees and reserves Conf_room1, Conf_room2, and Conf_room3.	—	—
