Chapter 8 Monitoring the Cisco Unified IP Phone Remotely Streaming Statistics • Core Dumps-Includes hyperlinks to individual dump files. The core dump files include data from a phone crash. • Status Messages-Displays up to the 10 most recent status messages that the phone has generated since it was last powered up. You can also see this information from the Status Messages screen on the phone. Table 7-2 describes the status messages that can appear. • Debug Display-Displays debug messages that might be useful to Cisco TAC if you require assistance with troubleshooting. 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 Accessing 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. Table 8-5 describes the items in the Streaming Statistics areas.
