Assistance Center. If your deployment relies on this serial console output for troubleshooting, we
recommend that you configure a syslog server to capture event messages from the TelePresence Server.
Disconnection of inactive calls
The TelePresence Server now responds to inactive calls by disconnecting them. If media is expected from
an endpoint but is not received for 30 to 45 seconds, then the TelePresence Server will disconnect the call.
When media has unexpectedly stopped in this way, the TelePresence Server will not show a frozen frame
from that stream; it will show no video until it disconnects the call (this aspect of the feature addresses issue
number CSCub64800).
This feature applies to any calls using H.323, SIP, or TIPcall protocols. If auto-reconnect is enabled for the
call, the TelePresence Server retries the call after disconnecting it.
The TelePresence Server will not disconnect a call if the endpoint has signaled that it is on hold or if the
media channels are muted.
Resolved issues
The following issues were found in previous releases and are resolved in 3.1(1.95).
Resolved since version 3.1(1.80)
Identifier Description
CSCuj88766 In some circumstances, negotiation that involves an unusually high number of SIPmedia lines
can cause the TelePresence Server to restart.
CSCuj54065 An error message such as the following may appear on a Cisco Multiparty Media 310/320 running
3.1(1.80): HEALTH_MONITOR Error sensor CC0 T0 core failed: reading 1127.000000
mV should be between 980 and 1120 mV. In 3.1(1.80), these messages may not be
indicative of a genuine problem. An upgrade to version 3.1(1.95) is advised so that genuine
voltage problems are not masked by spurious error messages.
CSCuj31071 Modifying a connected pre-configured endpoint using the participant.set APIcommand, on a
locally managed TelePresence Server API, could result in an erroneous fault: "Fault 5: 'no such
participant'" and an event log message "attempt to set attribute overrides for call with configured
endpoint".
This is now resolved.
CSCuj05358 Lipsync issues could be observed when endpoints connected at lower bandwidths (< 1Mbps),
with packet loss, and the TelePresence Server applied Forward Error Correction to the video
channel. This issue was observed on TelePresence Server MSE8710 and TelePresence Server
7010 platforms.
This is now resolved.
CSCui45750 Minor video quality issues were observed on 1080p30 calls on TX9000 series endpoints. These
issues included frame skips, background mottling, and blurring during high motion (eg. walking
across the camera field of view).
This has been improved in this release.
CSCuh35020 The online help pages highlighting the differences between different platforms did not have
equivalent detail for Cisco TelePresence Server on Virtual Machine.
This is now resolved.
