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. Cisco
Unified IP Phones 6900 Series use only Stream 1.
To display a Streaming Statistics area, access the web page for the phone as described in the “Accessing
the Web Page for a Phone” section on page 8-2 , and then click the Stream 1 hyperlink.
Table 8-5 describes the items in the Streaming Statistics areas.
