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 streams. 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 described in the
the Web Page for a Phone, page 8-2
, and then click the Stream 1, the Stream 2, the Stream 3, the
Stream 4, or the Stream 5 hyperlink.
