Cisco CallManager Initialization Process

In this section the initialization process of Cisco CallManager will be explained with the help of traces that are captured from CCM1 (identified by the IP address 172.16.70.228). As described previously, SDI traces are a very effective troubleshooting tool because they detail every packet sent between endpoints. This section will describe the events that occur when Cisco CallManager is initialized. Understanding how to read the trace helps you to properly troubleshoot the various Cisco CallManager processes, and the effect of those processes on services such as conferencing, call forwarding, and so on.

The following messages from the Cisco CallManager SDI trace utility show the initialization process on one of the Cisco CallManagers, in this case, CCM1. Review the descriptions of each message below.

The first message indicates Cisco CallManager started its initialization process.
