Overview The 3Com IP Conferencing Module is a multi-party conference
management program that supports a variety of communication modes and conference types. Users can participate in conferences that include voice, video, desktop sharing services, and instant messaging.
The 3Com IP Conferencing Module supports a variety of communication modes:
n Voice for Session Initiation Protocol (SIP) devices and analog phones
n Video for the 3Com Convergence Center Client
12 CHAPTER 1: 3COM IP CONFERENCING MODULE OVERVIEW
n Desktop sharing for the 3Com Convergence Center Client
n Instant messaging for the 3Com Convergence Center Client.
The 3Com Convergence Center Client includes the Presence Server, which collects and distributes the online status information of users.

Conference Types The following conference types are supported:

Scheduled — When a user sets up a scheduled conference, the required system resources are reserved for a defined period of time. After the conference ends, the resources become available again. User access can be restricted (password-protected) or public (accessible to anyone who knows the conference name). Scheduled conferences are configured on the web console.
Meet Me — Meet Me conferences are “always on,” without a scheduled start and end time. They are intended for informal meetings organized by regular users, and can be started only if sufficient resources are available on the system. User access can be restricted or public. Meet Me conferences are configured on the web console.
Ad Hoc — An Ad Hoc conference starts when the first user joins it. No configuration is required on the 3Com IP Conferencing Module. To activate the conference, the user simply dials a special prefix that has been set up by the administrator. Other users can join the conference by dialing the same prefix; no password is required. Ad Hoc conferences offer the same features as Meet-Me conferences for a maximum of six participants.
Instant — An instant conference starts as soon as the first participant calls it and dials the Conference Start PIN. The system then calls all other conference participants, who can join immediately or call the conference at a later time. If calling at a later time, users will be required to enter a password if the conference is restricted. Instant conferences can be configured by regular users on the web console.
Emergency — Emergency conferences are the same as instant conferences with the following exceptions:
n The system can be programmed to alert users that an emergency
conference is in progress by continuously ringing an alarm, flashing light, or other notification device.
Conference Feature Matrix 13
n Individual user extensions can be programmed with a line monitoring
feature that causes a lamp to flash whenever an emergency conference is in progress. The user connects to the conference by pressing the button located beside the lamp.
n Emergency conferences can be configured only by administrators.

Conference Names (IDs)

Every conference is identified by a unique SIP Uniform Resource Identifier (SIP URI) that is assigned when the conference is created. The SIP URI has a name portion and a server host portion. For example:
sip:7000@10.1.0.238
name server host
Only the name portion is required to connect the conference. Internal callers (callers within the enterprise) can simply dial the name and be connected directly. External callers (callers on the PSTN) must first dial the

Access Controls 15

Conference Attendant and then dial the name when prompted. Optionally, callers can dial the full SIP URI to reach the conference.
Conference names are always numeric (e.g. 7000). When users create a new conference, they can select a name from a block of numbers made available by the administrator (for example, any number between 7200 and 7299), or they can leave the conference name field blank, in which case the system will automatically assign a name from the available block of numbers.
In a multi-server configuration, the servers share a common range of numeric conference names (IDs). It is not possible to assign separate ranges to the individual servers in the pool.
Access Controls Conferences can be created with or without access controls.

Public Conferences Public conferences are unrestricted and open to anyone without the need

to authenticate or enter a passcode. The caller is only required to know the numeric conference ID.
Restricted
Conferences
Users access a restricted conference by authenticating themselves to the system. The authentication method varies depending on the conference type.
Scheduled and Meet Me
To access a restricted Scheduled or Meet Me conference, users are required to dial the numeric conference name and then enter a passcode to authenticate themselves and be added to the Participant Control List for the conference.
Instant and Emergency
When a restricted Instant or Emergency starts, the system calls a list of users and invites them to participate. Users who answer this call and press the # key are automatically authenticated and connected to the conference. Users who call the conference after it has started will be prompted to authenticate themselves by entering the Join PIN.
Users can call a conference after it has started by dialing the numeric conference name, or, if their extension has been programmed to support

Emergency Conference Notification, by pressing the appropriate line key on their telephone.

Licensing The 3Com IP Conferencing Module is activated by a set of license keys

that you must acquire from 3Com. There is a separate license key for each application:
n conference server
n conference attendant server
n presence server
The following feature levels are also controlled by the license keys:
Maximum Server
Capacity
G.729 Codec
Assignment

Media Type Defines which media types are supported by the conferences hosted on

For the conference server, this feature controls how many users can participate in conferences simultaneously. For example, if you purchase a license for 100 users, then a maximum of 100 ports are available on the server at any one time for conference participants.
For the conference attendant, this feature controls how many users can connect to the attendant IVR simultaneously.
For the conference server, this feature controls the number of ports that are available for G.729 connections. For example, if you assign 30 ports from a 100-port license to G.729, then these ports can use G.729 or any other supported codec (G.711, etc). The remaining ports cannot use G.729.
For the conference attendant, this feature controls how many users can connect to the attendant IVR simultaneously with G.729.
The number of ports you make available to G.729 depends on the processing capacity of your server. If you have a high-capacity server, you can allocate more ports to G.729.
the server. You can purchase support for audio, video and desktop sharing. This feature applies only to the conference server.
All licensing parameters are defined on a per-server basis.
Port Type Assignment 17

Port Type Assignment

The 3Com IP Conferencing Module connects to the network via ports. When you configure the ports in your system, you can subdivide them by type in order to optimize resource usage. For example, if your users hold a large number of impromptu meetings, then you should allocate most of your available ports to Meet-me and Ad Hoc conferences.
Available port types are illustrated in Figure 1.
Figure 1 Distribution of Port Types
Announcement

Conference
ports
1 Announcement ports — Used to deliver messages to users who are too
early or late to connect to a conference, or who attempt to join a conference that is locked or full. Announcement ports are available to deliver messages for all conference types (scheduled, meet-me, ad hoc, instant and emergency). By default, five ports are designated as announcement ports.
Scheduled
Non-Scheduled

2 Floater ports — Enables users to join conferences that are full, and
allows conferences to start when the system is near its maximum capacity. In the first example, if a conference has reached its provisioned limit of ten users and another wants to join, the extra user can be accommodated with a floater port. In the second example, if there are three conference servers, each of which is hosting a conference, and a user attempts to start another conference, the extra conference can be accommodated with floater ports. Depending on the total number of ports available, the system may support fewer users than actually provisioned for the extra conference.
3 Scheduled ports — Ports reserved for scheduled conference users. By
default, there are 25 scheduled ports.
18 CHAPTER 1: 3COM IP CONFERENCING MODULE OVERVIEW
4 Non-Scheduled ports — Ports reserved for Meet-Me, Ad Hoc, Instant
and Emergency conference users. By default, 25 ports are reserved for these types of conferences.
Total Number of Ports
Available
Port Usage per
Conference
Overbook Ports for
Scheduled
Conferences
The total number ports that you configure should equal the maximum server capacity (total number of licensed users). This can be expressed as:
Announcement ports Floater ports Scheduled ports Non-Scheduled ports maximum server capacity
When a conference starts, three ports are automatically allocated to it. Additional ports are allocated as more users join the conference. If any users fail to join, their ports remain available for use. For example, if you configure a scheduled conference for 10 users but only six participate, four ports will remain available for use by other scheduled conferences.
Overbooking allows you to reserve more ports for conferences than are actually available. Suppose you have 100 scheduled conference ports and that these are entirely booked for meetings. If the “overbook” parameter is set to 25, you can still schedule conferences for another 25 users.
Overbooking assumes that all users who are scheduled to attend often do not attend, which usually leaves unused ports available. In the rare case that all ports are scheduled and all people attend the meeting—including those who are overbooked—the last people to call into any meeting would not be able to get through.

Distributed Conferencing

In its standard configuration, the 3Com IP Conferencing Module concentrates all applications and processes on a single server. This limits the system to supporting a maximum of 300 conference participants at any one time.
In a distributed configuration, the applications and processes are assigned to multiple servers. A fully equipped system with twelve servers in a pool (ten for conferencing; two for provisioning, presence and database redundancy) can support up to 3,000 concurrent conference participants. Smaller systems with fewer servers can also be implemented.
Distributed Conferencing 19
Users employ a single web console to set up and manage their conferences, regardless of how many servers are installed.
To achieve maximum system capacity, the IBM xSeries 346 platform is required. Capacity is reduced with the IBM xSeries 306 platform.
Conference
Distribution
Mechanism
Conference Server
Roles (Routing and
Hosting)
When a new conference starts, the system uses the “best fit” distribution mechanism to assign it to the server in the pool that has the least available capacity (assuming that G.711 will be used for all connections, and that the conference will host the maximum possible number of users). If a server cannot be found with sufficient capacity, the conference is refused.
Conferences in a distributed system are handled by a pool of up to ten servers. The individual servers in the pool can host conferences, route callers to conferences, or perform both functions. A server in the routing role completes the following steps when a caller dials a conference:
n Receives the initial SIP INVITE message from the caller to the
conference.
n Uses the “best fit” distribution method to determine which server
should host the conference, or discovers which server is already hosting the conference.
n Redirects the caller to the conference.
Routing can be performed by any conference server in the pool. Simply configure the VCX dial plan so that calls are forwarded to the appropriate destination. If you have only one conference server (an “all-in-one” implementation), then only one route is required. If you have two or more conference servers, then at least two routes are required to provide redundancy. You can optimize system efficiency by assigning the routing role to all servers in the pool, or by restricting the number of ports available for conferencing on the “routing” conference servers.
Database
Redundancy
Database redundancy is provided to ensure that the system remains available in the event that a server fails. A single database pair (master and slave) is supported. The slave maintains a copy of the master using MySQL database replication. In the event that the slave cannot communicate with the master for ten minutes, switchover occurs. Manual switchover is also possible. Manual switchover is required whenever one of the application servers attempts to connect to the
20 CHAPTER 1: 3COM IP CONFERENCING MODULE OVERVIEW
wrong database server. (Note that this set-up only provides redundancy for server failure, not network failure.)

High Availability High availability is not provided as part of the solution. Each conference

runs on a single server, and if that server fails, then the conference participants are required to re-dial the conference and connect to a different server through the distribution mechanism described above.

Hostname Usage The servers in a distributed conferencing system will have distinct host

names. However, the domain name portion of conference addresses (@domain) will be the same for all conferences.

System Upgrades Following the initial implementation, the system can be upgraded in

order to increase system capacity or provide database redundancy. For example, adding a second server to a single-server implementation will provide database redundancy.
Upgrades can be performed at any time on fully operational systems. There is no need to disable any applications that are currently running when you add a new server.
Configuration
Options
Three basic configurations are possible. The type you select depends on the number of servers that are available, plus their processing capacity.
Configuration Option 1: Single Server
If you only have one server, then all components must be installed on it. Distributed conferencing is not a feature of this “all-in-one” solution.
Components installed on single server:
n conference server/conference attendant server
n presence server (if purchased)
n VCX user database
n conferencing and presence database
n web console server.
Configuration Option 2: Dual Server
If you have two servers, then both can host conferences. Implement database redundancy by installing the master database on one server and
Distributed Conferencing 21
the slave database on the other. Implement routing redundancy by configuring the SIP server to forward SIP INVITEs to both servers.
Components installed on the primary server:
n conference server/conference attendant server
n presence server (if purchased)
n VCX user database
n conferencing and presence database (initial master)
n web console server.
Components installed on second server:
n conference server/conference attendant server
n conferencing and presence database (initial slave).
Configuration Option 3: Four to Twelve Servers
If you have between four and twelve servers, configure the first server as a “provisioning” server by installing the web console server, presence server, VCX user database, and master database on it. Configure the second server with the slave database and, optionally, the conference server. Configure all other servers in the pool with the conference server. To ensure routing redundancy, configure the SIP server to forward SIP INVITEs to at least two servers in the pool.
Components installed on primary server:
n presence server (if purchased)
n VCX user database
n conferencing and presence database (initial master)
n web console server.
Components installed on secondary server:
n conferencing and presence database (initial slave).
Components installed on all other servers:
n conference server/conference attendant server.

User 1
User 2
1 A dial plan is used to redirect the initial call to a routing conference server.
2 The routing conference server uses the “best fit” distribution mechanism
to redirect the call to the conference server with the least available capacity (assuming that G.711 will be used for all connections, and that the conference will host the maximum possible number of users).
3 The user device calls the conference server specified by the routing
conference server and the conference is set up.
By default, presence information is concentrated on a single server—the primary server of the installation. However, you can distribute presence information across the enterprise by adding more installations of the 3Com IP Conferencing Module. Each installation has a single Presence server that is associated with one or more VCX systems.
Distributed Presence 23
For example, if you have two Presence servers and six VCX systems, then you can associate each Presence server with three VCXs. illustrates this example.

The link between Presence servers and VCX systems is made with mapping table entries. In a distributed environment with multiple Presence servers and VCXs, identical mapping table entries must be added to each installation of the 3Com IP Conferencing Module. In a non-distributed environment with one Presence server and one VCX, only one mapping table entry is required, which defaults to the values specified during the initial software installation.
Global Directory of
VCX Users
For each entry on the mapping table, you must specify whether Conference Provisioning is either allowed or denied. Selecting “allowed” enables users on other installations to provision conferences on the 3Com IP Conferencing Module that is associated with the local Presence Server. Selecting “denied” prevents non-local users from provisioning conferences.
For details, see Adding Distributed Presence/Conference Provisioning
Entries.
In addition to adding the mapping table entries, you must also add the Global Directory of VCX users to each installation of the 3Com IP
24 CHAPTER 1: 3COM IP CONFERENCING MODULE OVERVIEW
Conferencing Module. A properly configured Global Directory that includes entries for all regional offices (Chicago, Detroit, New York, Houston, Dallas and Phoenix in the above example) enables users to track the presence status of their buddies located throughout the network. For details, see

Audio CODECs The 3Com IP Conferencing Module supports conference participants using

any combination of the supported CODECs (the audio conferencing
trans-codes as required). Currently, the following CODECs are supported:
