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

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
(integration applications)
(integration applications)
In large IP deployments, multiple MeetingPlace IP integration
applications 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.)

Extended echo cancellation
limit for line echoes
limit for line echoes
Previous releases of MeetingPlace provided echo cancellation per port
for up to 128ms of line echo. With this release, in specific IP
deployments where the line echo exceeds the current limit, you may
extend this to up to 350ms of echo tail. This option is configurable only
through MeetingPlace Customer Support. For details, contact your
Cisco MeetingPlace support representative.
