When a call arrives at a Unified CVP ingress gateway, Cisco IOS assigns that call (regardless of whether 
SIP or H.323 is being used) a 36-digit hexadecimal Global Unique Identifier (GUID) that uniquely 
identifies the call. Unified CVP carries that GUID through all of the components that the call encounters, 
as follows:

Ingress gateway — shown in Cisco IOS log files

VoiceXML gateway — shown in Cisco IOS log files

Unified CVP components — shown in Unified CVP log files

Unified Intelligent Contact Management Enterprise (ICME) — shown in the Extended Call Context 
(ECC) variable user.media.id and stored with all Termination Call Detail (TCD) and Route Call 
Detail (RCD) records

Automatic speech recognition (ASR) and text-to-speech (TTS) servers — shown in logs as the 
logging tag

Cisco Unified Communications Manager (Unified CM) — appears in the detailed logs

Thus, with proper levels of logging enabled, a call can be traced through all of the above components.

The Unified CVP logs are located in $CVP_HOME\logs. All of the Unified CVP logs roll over at 
12:00 AM every night, with the date as part of the filename. The format of the date is yyyy-mm-dd. All 
of these logs will also roll over when they reach the predefined size limit of 100 MB and will have a 
number as part of the filename extension. The number indicates which log it was for that day. When the 
entire logs directory reaches a predefined size, old files are purged as necessary.

For more information on Unified CVP logging, see the Troubleshooting Guide for Cisco Unified 
Customer Voice Portal, available at 

Although Unified CVP components do not themselves synchronize machine times, customers must 
provide a cross-component time synchronization mechanism, such as NTP, in order to assure accurate 
time stamps for logging and reporting.

The Unified CVP Reporting Server houses the Reporting Service and hosts an IBM Informix Dynamic 
Server (IDS) database management system.

The Reporting Service provides historical reporting to a distributed self-service deployment in a call 
center environment. The system is used to assist call center managers with call activity summary 
information to manage daily operations. It can also provide operational analysis of various IVR 
applications.

The Reporting Service receives reporting data from the IVR Service, the SIP Service (if used), and the 
Unified CVP VXML Server. (To capture the data from the Unified CVP VXML Server in the 
Unified CVP Reporting Server's database, the Unified CVP VXML Server should be added by using the
