Cisco Systems OL-11303-01 manual Failed Incoming Calls, Dropped Calls

Chapter 3 Common Telephone Issues in Cisco Unified MeetingPlace Express

Failed Incoming Calls

•Check if G.729 coders are being used somewhere in your network, instead of G.711. G.729 will seriously corrupt in-band digits (DTMF) causing these digits to either be lost or changed. If this is happening and RFC 2833 is not a good choice, consider converting to a pure G.711 network.

Failed Incoming Calls

If you are not able to receive incoming calls, do the following:

Procedure

Step 1 Log in to the Cisco Unified MeetingPlace Express operating system as the root user.

Step 2 At the password prompt, enter the root password.

The Cisco Unified MeetingPlace Express operating system desktop appears.

Step 3 Right-click on the desktop.

Step 4 From the menu, select New Terminal. This brings up a terminal session.

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 Determine if the Cisco Unified MeetingPlace Express system registered the call signaling packets.

•If the system registered the call, look for a reason in the trace log why the call was disconnected. Enter one of these commands:

eventlog -b<mmddhhmm> -e<mmddhhmm> -v

eventlog -b<mmddhhmm> -e<mmddhhmm> -G -v

•If the system did not register the call in the trace log, the problem might be a configuration problem on the device that routes calls to Cisco Unified MeetingPlace Express. Also, check if any firewalls may be preventing the call from reaching the system.

Dropped Calls

	If calls are connected to the system, but then disconnect during the call, do the following:
	Procedure
Step 1	Log in to the Cisco Unified MeetingPlace Express operating system as the root user.
Step 2	At the password prompt, enter the root password.
	The Cisco Unified MeetingPlace Express operating system desktop appears.
Step 3	Right-click on the desktop.
Step 4	From the menu, select New Terminal. This brings up a terminal session.
