Hi Cris,
In UC 7.x this is now available via RTMT (Real Time Monitoring Tool). Works great!
Port Monitor Overview
The RTMT Port Monitor lets you monitor the activity of each Cisco Unity Connection voice messaging port in real time. This information can help you determine whether they system has too many or too few ports.
This tool can display the following information for each port:
Port Name The display name of the port in Cisco Unity Connection Administration.
Caller For incoming calls, the phone number of the caller.
Called For incoming calls, the phone number that was dialed.
Reason If applicable, the reason why the call was redirected.
Redir The extension that redirected the call. If the call was redirected by more than one extension, this field shows the extension prior to the last extension.
Last Redir The last extension that redirected the call.
Application Status The name of the conversation that Cisco Unity Connection is playing for the caller. When the port is not handling a call, the status specifies "Idle."
Display Status The action that the conversation is currently performing. When the port is not handling a call, the status specifies "Idle."
Conversation Status Specific details about the action that the conversation is performing. When the port is not handling a call, the status specifies "Idle."
Port Ext The extension of the voice messaging port.
Connected To For Cisco Unified Communications Manager SCCP integrations, the IP address and port of the Cisco Unified Communications Manager server to which the voice messaging ports are registered.
