Supporting up to 960 IP connections, Release 5.2.1 works with the Cisco Unified MeetingPlace Audio
Server system to provide meeting access to callers. The Cisco Unified MeetingPlace Audio Server
system supports connections from up to sixteen IP-gateway servers; this multigateway support provides
network load balancing and system redundancy.
To deploy Release 5.2.1, your network must have following system components:
•Cisco Unified MeetingPlace Audio Server system to provide conferencing functionality.
•Release 5.2.1 to perform IP call setup and tear down for the Cisco Unified MeetingPlace Audio
Server system.
•Endpoints that are supported by Release 5.2.1 to connect callers to the Cisco Unified MeetingPlace
Audio Server system.
•One of the following applications to route IP calls to the IP-gateway server:
– Cisco Unified CallManager
– Cisco SIP Proxy Server
– Cisco Gateway
Note If you are using an IP PBX that runs standard H.323 or SIP call control, see the “Information About
Configuring Cisco Unified MeetingPlace H.323/SIP IP Gateway Software Release 5.2.1” section on
page 3-1 for the required system settings and see your IP PBX documentation for information about how
to configure these settings.
Cisco Unified MeetingPlace System
Consisting of the Cisco Unified MeetingPlace Audio Server system and a variety of integration
applications, the Cisco Unified MeetingPlace system is an integrated communication and productivity
tool that is deployed on a corporate network behind the firewall. With the Cisco Unified MeetingPlace
system, users in different locations can collaborate in real time by sharing documents over personal
computers and discussing content over telephones.
Access to the Cisco Unified MeetingPlace system is easy through end-user desktop applications, such
as web browsers and instant messaging clients. The Cisco Unified MeetingPlace system also integrates
with groupware clients and PSTN and IP-based telephones. Because of this access and integration, users
can quickly schedule and attend Cisco Unified MeetingPlace meetings from any location by using their
preferred interfaces.

IP telephony uses your data network infrastructure to transmit voice packets. The underlying technology
that is used by IP telephony applications is Voice over IP (VoIP), which enables different types of
endpoints—IP phones, PSTN phones, and H.323 clients, for example—to communicate over your
network.
The following sections provide information about VoIP concepts and how they relate to Release 5.2.1:
•Standards That are Supported by Cisco Unified MeetingPlace H.323/SIP IP Gateway Software
