Tracing
• Trunk group trunk-level trace traces only calls for a given trunk (or CIC). Use this format if the trunk
group and trunk on which the call is placed is known.
sta-sc-trc: trkgrp :trk= w
Note See Cisco PGW 2200 Softswitch Release 9 MML Command Reference for detailed information
on using the sta-sc-trc command.
Step 2 Make the call.
Starting A Call Trace (on Release 9.7(3) Patch 8)
You can perform advanced call traces starting from Cisco PGW 2200 Softswitch Release 9.7(3) Patch 8.
The advanced call trace is based on the existing call trace function and adds the calling party number,
the called party number, the MCL (Machine Congestion Level) setting, the cause value, and the call
duration as call trace criteria. This enhancement makes the call trace more accurate and reduces system
performance impacts on the Cisco PGW 2200 Softswitch when it is performing call traces.
To start the call trace, perform the following steps:
Step 1 Log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter the command.
You can enter this command in either of the following two formats:
sta-sc-trc:<sig_path>:[span=x[,rng=y][,tc=z[,rng=w]]][,anubmer=”calling party
number”][,bnumber=”called party number”][,causevalue=c][,incompleteoverlapnumber]
[,duration=d][,mcl=m][,autostop][,prd=n][,log=”log”],confirm
sta-sc-trc:<trunkgroup>:[trk=x[,rng=y]][,anubmer=”calling party number”][,bnumber=”called
party number”][,causevalue=c][,incompleteoverlapnumber][,duration=d]
[,mcl=m][,autostop][,prd=n][,log=”log”],confirm
Table 6-3 provides a parameter list for this sta-sc-trc MML command.
