ActiveControl to endpoints
ActiveControl is a new feature of the TelePresence Server that improves the conference experience for
participants in conferences hosted on TelePresence Servers. The feature is used on a per call basis when
the TelePresence Server is remotely managed. There are no web interface settings for ActiveControl and it
does not require any configuration.
Notes:
n This feature is only available in the remotely managed mode of TelePresence Server operation. It is not
available in the locally managed mode.
n The iXprotocol that enables ActiveControl is disabled by default because it is not recognized by some
older systems, including Cisco Unified Communications Manager versions earlier than 9.0. You can
enable the protocol on a per call basis, using the API, but be aware that this may have unpredictable
consequences, including call failure, if there are such older systems in the call path.
If you wish to use the ActiveControl feature with Cisco Unified CM, then we recommend that you connect
your TelePresence Server to a Cisco Unified CM running version 9.1.2 or later (although versions 9.0 and
9.1 also recognize iX). You should also disable the iXChannel on trunks between that Cisco Unified CM
and others that are running pre- 9.0 versions (uncheck Allow iX Application Media checkbox in the
Trunk Specific Configuration section of the SIP Profile Configuration window).
Refer to the Optimized Conferencing for Cisco Unified CM and Cisco VCS Release 2.0 Solution Release
Notes, at http://www.cisco.com/en/US/products/ps11775/prod_release_notes_list.html, for more details
on enabling iX within your Optimized Conferencing deployment.
n ActiveControl cannot currently traverse firewalls.
The features enabled by ActiveControl require corresponding support in the endpoints' software and user
interfaces to maximize their potential. This feature is supported on endpoints that are running TC version 6.2
