About the API xConfiguration
New features and improvements
Cisco Unified Communication Manager (CUCM)
redundancy support
The TelePresence endpoints have CUCM redundancy
support with failover and fallback. The TelePresence endpoint
will automatically register to the next CUCM in the cluster if
the connection to the active CUCM is lost.
If the TelePresence endpoint loses its connection to the
primary CUCM, the call is preserved, but no additional
features like content sharing, putting participants on hold
etc. will be available. The next call will be handled by the
secondary CUCM and all call features are available again.
When the primary CUCM is back online, the endpoint will
automatically register with the primary CUCM.
More details can be found in the Administering TC endpoints
on CUCM guide for TC6.2.
Improved provisioning from CUCM
Several TelePresence endpoint parameters are added to
CUCM and can be provisioned to the endpoint.
More details can be found in the Administering TC endpoints
on CUCM guide for TC6.2.
Support for CUCM provisioning of the endpoint password
when using the encrypted security profile
TelePresence endpoints can be fully and securely provisioned
from CUCM. When the TelePresence endpoint is set up with
an encrypted security profile in CUCM, the endpoint will read
the admin password from the CUCM. The password can not
be empty, and the user name must be admin.
More details can be found in the Administering TC endpoints
on CUCM guide for TC6.2.

Support for auto discovery of the CUCM
The TelePresence endpoints have support for auto discovery
of the CUCM through DHCP Option 150. If the network
provides the CUCM address through DHCP Option 150,
the endpoint will automatically register to the CUCM after a
factory reset.
More details can be found in the Administering TC endpoints
on CUCM guide for TC6.2.
Support for IPv4, IPv6 and dual stack
The video system is able to operate on IPv4, IPv6 or both
at the same time (dual stack). This is configured using the
xConfiguration Network IPStack setting. Which IP version
to use for calls is configured using the xConfiguration
Conference CallProtocolIPStack setting.
G.729 audio codec support in H.323 calls
Support for the G.729AB audio codec is added in H.323 calls
in order to provide better IP phone interoperability. G.729 has
been supported in SIP calls as from software version TC6.1.
Lync 2013 support for point-to-point calls
You can set up video calls between TelePresence systems
and Lync 2013 users. HD quality at full frame rate (720p30)
is supported in both directions. This feature is disabled
by default. It must be enabled using the xConfiguration
Conference LyncCompatibility Mode setting. It also requires
version X8 of the VCS (Video Communication Server).
You can see the Lync 2013 users in the TelePresence
system's directory (phone book), provided that TMS
(TelePresence Management System) version 13.x or later is
used.
