Dead Air During Calls

Step 5 At the CLI, enter the following:

eventlog -b<mmddhhmm> -e<mmddhhmm>

For the start time (the -b value), enter a time shortly before the call failed. For the stop time (the -e value), enter a time shortly after the call failed.

Step 6 Check for a “far end disconnect event.” If you see this, the disconnect may have been initiated outside of the Cisco Unified MeetingPlace Express system. Check for errors on the devices between the phone and the Cisco Unified MeetingPlace Express system.

Step 7 If you do not see a “far end disconnect event,” the Cisco Unified MeetingPlace Express system hung up on you first. Review the trace log to try to determine why the system hung up on you.

Step 8 If your system uses Cisco Unified CallManager contact the Cisco Unified CallManager network administrator to get a call session trace indicating why Cisco Unified CallManager sent the disconnect event to you.
