Time-stamping of the trace output can be enabled or disabled by the user.
The telephony switch protocol can be traced, but the output is encoded for security.
9.6.1 Trace Format
The following is a description of the format of a trace display. The example display is broken down
into its components.
Example of trace display:
003:02:372 [Tel-2 ] Event Lamp 60:CallApp0:0 FLASH->OFF
Components:
003:02:372 - time-stamp in minutes:seconds:milliseconds
[Tel-2] - trace-key and telephony port (no port if non port-related)
Event - trace type
Lamp 60:CallApp0:0 FLASH->OFF
9.6.2 Trace Utility
The trace utility separates the control of software module trace output using trace keys. A single
trace key represents a functional software module. The trace utility then uses trace types that can be
enabled or disabled for each trace key. The trace keys and trace types are used to enable or disable
traces using the trace utility.
9.6.2.1 Trace Key
The trace key defines the specific sub-system within the Media Gateway to trace. For example, if
you are only interested in capturing SIP packets (SIP Emulating or SIP Driving mode), you would
use the VoIp trace key:
trace voip <trace type> on
Table 19 describes all trace keys supported by the trace function as well as the trace types available
to each trace key.
