Chapter 7 Viewing Security, Device, Model, and Status Information on the Phone
Viewing the Phone Status Menu
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,
follow these steps:
Procedure
Step 1 Press Settings > Status.
Step 2 Scroll to and select Call Statistics; the list of statistics appears.
Step 3 Use the Navigation button to scroll through the items in the Call Statistics screen.
Table 7-6 describes the items that appear in this screen.
Step 4 To exit the Call Statistics screen, press the Back softkey.
