A feature of the CyberSWITCH console is the ability to save and display a record of the high level
ISDN calls between the system and the local telephone switch. If calls are unable to be completed,
this is normally the first area to look.
Call Trace puts messages into the Report log that can be read by using the
dr
command. Call Trace
is enabled by using the
trace on
command, and disabled by
trace off
.
The following is a description of the possible fields included in a Call Trace Message:
1.
The <Call Id> field in the message can be used to keep track of messages for the same phone
call. This is useful when a system is making more than one call at a time.
2.
The In-Disconnect and In-Information messages have a location field. This identifies where the
message originated.
The following chart provides a list of locations that may appear in Call Trace messages:
3.
The In-Disconnect messages have a cause field. This is the value (in hex) that was in the
message. It explains why either a call was disconnected or why a call attempt was not able to
be completed. There are also parameters (such as <signal value>, <progress value>), that are
not described here. These values represent messages reported from the switch. We have
attempted to interpret their significance in the error message text itself.
Refer to the
Cause Codes
table, for a complete listing of cause codes.
When the call trace option is enabled, the system may report messages such as:
