Define FTP servers
When you set up your Cisco® CallManager device to collect CDR/CMR data, you can also designate an FTP server where the data is stored so that other applications, such as VoIP and Network Quality Manager can download and process the data. For more information about FTP configuration, see Configure Cisco CallManagers for FTP.
If you are unsure of your FTP server settings, check your Cisco Billing Application Server parameters.
The Polling Frequency refers to how frequently VoIP and Network Quality Manager tries to download CDR/CMR data. If you have a large amount of data or if VoIP and Network Quality Manager experiences frequent timeouts, you should extend the amount of time between polls.
Deleting CDR/CMR data can cause serious data loss, but can be useful in certain circumstances. Do not select this option unless you successfully run verified backups of your data.
