How to setup Call Detail Records(CDR) from CUCME and Tips

There are three ways to configure CDRs receiving from Cisco Unified Call Manager Express.
 

– Syslog Server
– RADIUS Server
– FTP Server

1. Syslog Server

1.-1. Pros

– Low Cost
– Quick Install
– Easy to configure
– Easy to interpriet (CSV format)
 

1-2. Cons

– Hard to read and parsing software needed.
– No CDR backup
– Syslog works over UDP(514)
 

1-3. Configuration

CUCME_Router(config)# Service timestamps log datetime msec localtime
CUCME_Router(config)# aaa new-model
CUCME_Router(config)# aaa authentication login default none / local
CUCME_Router(config)# aaa accounting connection h323 start-stop radius
CUCME_Router(config)# gw-accounting syslog
CUCME_Router(config)# logging host x.x.x.x ; syslog server IP

2. RADIUS Server

2.-1. Pros

– More details accounting
– Real-time application support
– Customized setting and records
– Vendor Specific Attributes(VSA)
– Multiple Server support
– Captures can be stored in flash
 

2-2. Cons

– Complext setup
– RADIUS system required

 

2-3. Configuration

CUCME_Router(config)# Service timestamps log datetime msec localtime
CUCME_Router(config)# aaa new-model
CUCME_Router(config)# aaa accounting connection h323 start-stop broadcast group radius
CUCME_Router(config)# aaa session-id common
CUCME_Router(config)# radius-server host x.x.x.x
CUCME_Router(config)# radius-server vsa send accounting
CUCME_Router(config)# radius-server vsa send authentication

3. FTP Server

3.-1. Pros

– Low cost
– Quick and easy setup
– Easy to interpriet (CSV format)
– Reliable transport(LAn/WAN)
– CDR can be stored at flash
 

3-2. Cons

– No Real-time application support
– CPU intensive
– FTP Server system required

 

3-3. Configuration

CUCME_Router(config)# Service timestamps log datetime msec localtime
CUCME_Router(config)# gw-accounting aaa
CUCME_Router(config)# gw-accounting file
CUCME_Router(config)# primary ftp x.x.x.x username [username] password [password]
CUCME_Router(config)# maximum buffer-size 15
CUCME_Router(config)# maximum retry-count 3
CUCME_Router(config)# maximum fileclose 3
CUCME_Router(config)# maxmum cdrflush-timer 245

3-5. Troubleshooting

– When file is stopped to send.
 

Solution 1> Reconfigure ‘gw-accounting file’

CUCME_Router(config)# no gw-accounting file
CUCME_Router(config)# gw-accounting file

 

Solution 2> force the sending of the CDR using the command:

CUCME_Router#file-acct flush with-close
