Monitoring the Cisco Unified IP Phone  
Remotely  
Each Cisco Unified IP Phone has a web page from which you can view a variety  
of information about the phone, including:  
Device information  
Network configuration information  
Network statistics  
Device logs  
Streaming statistics  
This chapter describes the information that you can obtain from the phone’s web  
page. You can use this information to remotely monitor the operation of a phone  
and to assist with troubleshooting.  
You can also obtain much of this information directly from a phone. For more

Streaming Statistics  
Streaming Statistics  
A Cisco Unified IP Phone can stream information to and from up to three devices  
simultaneously. A phone streams information when it is on a a call or running a  
service that sends or receives audio or data.  
The streaming statistics areas on a phone’s web page provide information about  
the streams. Most calls use only one stream (Stream 1), but some calls use two or  
three stream. For example, a barged call uses Stream 1 and Stream 2.  
To display a Streaming Statistics area, access the web page for the phone as  
then click the Stream 1, the Stream 2, or the Stream 3 hyperlink.
