Verify the QSIG Configuration
Step 9 show rawmsg
Use this command to display information about memory leaks.
Step 10 show running-config
Use this command to display basic router configuration.
Step 11 show voice port [slot/port | summary]
Use this command to display summary information about voice-port configuration.
Troubleshooting Tips
• Use the debug cdapi {events | detail} command to display information about CDAPI application events, registration, messages, and more.
• Use the debug isdn event command to display events occurring on the user side (on the router) of the ISDN interface. ISDN events that can be displayed are Q.931 events (call setup and teardown of ISDN network connections).
• Use the debug tsp command to display information about the telephony-service provider (TSP).
