G.729a compression codec 
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. 
N
OTE
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 
MeetingPlace 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 
(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
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
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.
