The TelePresence Server overlays these icons, when appropriate, over the video streams composed and
sent to endpoints. If ActiveControl is enabled, the TelePresence Server sends the icon state information to
endpoints so that endpoints can use their own indications (where supported).
Improved mute behavior
In previous releases, muting an endpoint from the TelePresence Server side would cause the endpoint to be
removed from the list of previous loudest speakers, and that participant's video could disappear suddenly
from the layout.
In this release, the behavior has been improved so that muting an endpoint from the TelePresence Server's
web interface, or via ActiveControl, behaves in the same way as if the participant had muted the endpoint.
The endpoint remains in the previous loudest speakers list and the video does not suddenly disappear from
the layout.
Suppress audio during DTMF
The TelePresence Server now suppresses the audio coming from an endpoint when the TelePresence
Server is sending the connection DTMFsequence to the endpoint, so that other participants do not hear the
audio from the endpoint while it is connecting.
The audio suppression continues until the whole DTMFsequence is complete, even if the sequence contains
leading or trailing commas - which create pauses of two seconds each.
This suppression is independent of other audio muting options and also persists during retries. This is
necessary in combination with the persistence feature because, if the TelePresence Server needs to redial
an endpoint in the middle of the conference, the other participants should not hear the audio from the endpoint
while it is connecting.
Note:the maximum length of the DTMFsequence has been extended to 127 characters. In prior versions
there was a 31 character limit.
Improved room switching
This release improves the way that TelePresence Server displays video from systems with multiple
cameras, screens, and microphones ("multi-screen endpoints", for shorthand) to other conference
participants using multi-screen endpoints.
The TelePresence Server can now use streams from a multi-screen endpoint to fill large panes that would
otherwise be left blank if someone using that endpoint was not the loudest speaker.
For example, consider a conference in which all participants are using three-screen endpoints except for two
who are using single-screen endpoints. In the previous releases, when one of the participants using a single-
screen endpoint was the active speaker, the TelePresence Server would send the feeds from the two single-
screen endpoints to all the three-screen endpoints, and would fill the third screen of those endpoints with a
blank / empty feed.
In the same scenario, this release of the TelePresence Server uses a feed from one of the other multi-screen
endpoints in place of that blank pane, to make sure that all the endpoint's screens are used.
Content support up to FullHD on Immersive Cisco TelePresence
endpoints
The TelePresence Server can now support content streams of up to Full HDresolution to and from TIP-
capable endpoints.
