Viewing Model Information, Status, and Statistics on the Conference Station

Status Menu

Call Statistics Screen

The Call Statistics screen displays information about the last call on the conference station.

Table 7-2

describes the information displayed on the screen.

Note

You can remotely view the call statistics information by using a web browser to access the

Streaming Statistics web page. For more information about remote monitoring, see

Chapter 8,

“Monitoring the Conference Station Remotely.”

A single call can have multiple voice streams, but data is captured for only the last voice stream. A voice

stream is a packet stream between two endpoints. If one endpoint is put on hold, the voice stream stops

even though the call is still connected. When the call resumes, a new voice packet stream begins, and the

new call data overwrites the former call data.

To display the Call Statistics screen for information about the last voice stream, choose

IP address and UDP port of the conference station.

Start Time

Internal time stamp indicating when Cisco Unified Communications

Manager 6.0 requested that the conference station start transmitting

packets.

Codec Type

Type of voice stream received or transmitted (RTP streaming audio): G.729,

G.711 u-law, G.711 A-law, G.722, G.722.1, or Lin16k.

Avg Jitter

Estimated average RTP packet jitter (dynamic delay that a packet

encounters when going through the network) observed since the receiving

voice stream was opened.

Max Jitter

Maximum jitter observed since the receiving voice stream was opened.
