device. The TCP handle value for the device remains the same until the device is rebooted or
goes offline.
In the following traces, the Cisco IP Phone (1001) has gone off-hook. The trace shows the
unique messages, TCP handle, and the calling number, which is displayed on the
Cisco IP Phone. There is no called number at this point, because the user has not tried to dial any
digits.

In the following traces, the user is dialing the 3333, one digit at a time. The number 3333 is the
destination number of the phone, which is located somewhere on the PSTN network. The digit
analysis process of the Cisco CallManager is currently active and is analyzing the digits to
discover where the call needs to get routed. A more detailed explanation of the digit analysis was
provided in the previous case study.

In the following traces, the digit analysis has been completed, calling and called party has been
matched, and the information has been parsed.

In the following traces, the number 0 indicates the originating location, and the number 1
indicates the destination location. The bandwidth of the originating location is determined by
BW = –1. The value –1 implies that the bandwidth is infinite. The bandwidth is infinite because
the call was originated from a Cisco IP Phone located in a LAN environment. The bandwidth of
the destination location is determined by BW = 64. The call destination is to a phone located in a
PSTN, and the codec type is used is G.711 (64Kbps).

The following traces show the calling and called party information. In this example, the calling
party name and number is the same because the administrator has not configured a display name,
such as “John Smith.”
