What’s new in this release
MeetingPlace Audio Server 5.2 includes the following new features.
Feature
Description
Voice Over Internet Protocol (VoIP) enhancements
VoIP scalability
MeetingPlace 8112 systems can now scale to a maximum of 960 IP
ports. MeetingPlace 8106 systems can scale to a maximum of 480 IP
ports. All current MeetingPlace features, including in-session features,
are identical. (For more information, see

SIP protocol support
Session Initiation Protocol (SIP) is an IP telephony protocol developed
by the IETF. It is modular in nature and provides extensions for
presence and mobility applications. In this release, MeetingPlace
supports SIP, in addition to H.323 for IP call control. MeetingPlace can
handle H.323 and SIP calls simultaneously, adding flexibility to
environments that have multiple IP call controls.

G.729a compression codec
support
support
MeetingPlace IP currently supports G.711 codecs, which takes up 64
Kbps of bandwidth per call and has the best voice quality of all
available codecs. When deploying Voice Over IP, customers may
decide to use the G.729a compression codec for connections where
bandwidth is scarce. For this reason, MeetingPlace IP supports G.729a
compression codec for conferencing in this release. However, for
optimal voice quality, G.711 is recommended.

By default, MeetingPlace is configured to G.711 only. To
configure MeetingPlace to accept G.729a, see the Cisco MeetingPlace
Audio Server 5.2 Customer Engineer Guide, or contact your Cisco
Audio Server 5.2 Customer Engineer Guide, or contact your Cisco
customer support representative.
Hold and transfer feature
MeetingPlace IP Gateway allows VoIP users to put a line on hold,
including a line to a MeetingPlace conference, from their handset to
answer, transfer, or outdial another call on a multi-line phone. In the
same way, users can perform simple phone transfers via the handset
during meetings.

Multiple IP Gateways
In large IP deployments, multiple MeetingPlace IP Gateways can be
deployed against a single 8100 series system to provide load balancing
and system redundancy. Calls can be routed round-robin to the IP
gateways. If one IP gateway fails, calls that are in session will fail;
however, new callers will be routed to the alternative IP gateway to
connect with the audio server.

Registration, Admission, and
Status (RAS) support
Status (RAS) support
RAS is part of the H.323 protocol that refers to the management of IP
devices through registration with a gatekeeper. Typically, this is not
required for Cisco Call Manager or Avaya Communication Manager IP
deployments, but may be needed for integrated IP video deployments.
MeetingPlace IP can now support registration requirements on an IP
network. (For configuration details, see the MeetingPlace IP Gateway
5.2 System Manager’s Guide.)
