pass is"
The response indicates whether the audit passed or failed. If the audit failed, see the documentation for
the associated MGCP media gateway for more information on troubleshooting the identified problem.
To retrieve an audit that is run on all the MGCP media gateways, log on to the active Cisco PGW 2200
Softswitch, start an MML session, and enter the
rtrv-aud-gw:all command.
The system returns a response like the one shown previously, with a set of data for every MGCP media
gateway that is associated with your system.
Running a Manual Continuity Test
To run a manual continuity test (COT) on a specified remote switch CIC, log in to the active Cisco PGW
2200 Softswitch, start an MML session, and enter the
tst-cot: sig_srv :cic= number command.
Where:
• sig_srv—MML name of the signaling service that is associated with the CIC that you want to test.
• number—Identification number of the CIC that you want to test.
For example, to run a manual COT on CIC number 5 of a signaling service named sigsrv1, you would
enter the
tst-cot:sigsrv1:cic=5 command.
If the manual COT test fails, verify the COT settings for the Cisco PGW 2200 Softswitch and the
associated media gateway, as described in the “Verifying Continuity Test Settings” section on
page 6-149.
Verifying Continuity Test Settings
Step 1 If you have not already collected system data, refer to the method that is described in the “Collecting
System Data for Cisco TAC” section on page 6-93.
Step 2 Verify that the COT properties for the associated SS7 signaling service or trunk group are correct by
logging in to the active Cisco PGW 2200 Softswitch, starting an MML session, and entering the
prov-rtrv: component :name=" comp_name " command.
Where:
• component—MML component type name for the SS7 signaling service or trunk group properties.
Enter one of the following:
– sigsvcprop—Component type for SS7 signaling service properties.
– trnkgrpprop—Component type for trunk group properties.
• comp_name—MML name for the affected SS7 signaling service or trunk group.
For example, if you wanted to verify the properties for an SS7 signaling service that is called ss7svc1,
enter the
prov-rtrv:sigsvcprop:name="ss7svc1" command:
