Processing data from CUBE supplies a more holistic view of an organization’s PSTN calling. CUBE does not have to route calls to a CUCM cluster; it can route calls to a third-party application like a fax server or an interactive voice response system. Doing so can give you visibility into calls that CUCM doesn’t natively offer.
The only calls CUCM sees involving CUBE are PSTN calls sourced or destined to a registered endpoint (phone, CCX port, Unity). CUBE, on the other hand, will only see PSTN-facing call activity. It will not include CUCM intra-cluster call records.

Multiple event records are logged for each call routing via a CUBE device. For instance, each normal two-way call will have at least two events uniquely identified by the h323 call origin (Answer, Originate, or Call Back).
The benchmark stats pulled from a sample data set are below. It represents the general specifications based on 650,000 events stored in the Variphy database.

Example Data Sizing
The following high-level items are required to enable FTP access for CUBE:
The OVA comes with FTP preinstalled but disabled by default.
Example:
add-ftp-user -n USERNAME -p PASSWORD -d CDR_DATA_DIRECTORY
If you are using a Variphy version prior to v12.3, click here to learn how to update.
If your license is coded to allow CUBE devices, the user will see a new CUBE/IOS cluster type.
Here’s how to set up Variphy CUBE.
Note the field for the IP address of CUBE. We will use this for informational purposes only at this time.
5. Select the time zone that this CUBE device resides in.
Data Processor Status: Current Status of data processing. The status will remain disabled until the CUBE cluster type is activated and the database created.
CDR File Delivery: The subfolder name within the root directory to which you are delivering data. For Linux this will likely read /opt/variphy/data/CUBE/.
Process Files Every: Use System Default refers to global setting defined in Settings > System > Application Settings.
Preserve Files After Processing: Use System Default refers to global setting defined in Settings > System > Application Settings.
Database Server: Select the predefined Database Server defined on Settings > System > Database Servers.
NOTE — Using the Variphy OVA will default this setting to the local database engine.
Database Name: Indicate a unique database name that will be created to hold your CUBE data. The initial setup will create the database and write the schema to the selected database server with this supplied name.
Purge All CDR Data: The amount of CUBE data to retain in the database before a nightly purge.
Purge Connected Zero Duration Call CDR Data: Ability to delete CUBE data that is connected but has a zero duration at a different pace.Purge Non-Connected Call CDR Data: Ability to delete CUBE data that is Non-Connected at a different pace than Connected / 0 duration events.
Purge CDR Daily At: Time at which you’d like to run the purge cycle.
Purge Batch Count: Default 1000. Number of records handled by each deletes statement.
Purge Max Duration: The allowed time to run the purge process. In this example, it will run threads (LIMITS) of 1000 records for a duration of 2 hours daily until all necessary records are deleted.
To show all vsftpd users:
cat /etc/vsftpd.userlist
To validate that the firewall is disabled:
sudo ufw status
To check the FTP user home directory. In the below example, we are validating the variphyftp user home directory:
cat /etc/passwd | grep variphyftp
To change the FTP user's home directory. In the below example, we are changing the home directory for the variphyftp user to /opt/variphy/data/CUBEdata:
sudo usermod --home /opt/variphy/data/CUBEdata variphyftp
To reset the vsftpd users password. In the below example, we will change the FTP password of the variphyftp user:
sudo passwd variphyftp
To show the VSFTPD log file:
cat /var/log/vsftpd.log
To show the files contained in flash:
show flash:
To show the file accounting configurations on the CUBE:
sh run | begin gw-accounting file
To manually FTP copy a file from flash:
copy flash:filename ftp://userid:password@FTPServer
Force the file accounting configurations to run now:
file-acct flush with-close
Rest the file accounting routine. Used when file accounting stops pushing data and needs to be restarted:
file-acct reset
Show active CUBE calls. Useful to see calls before forcing a push:
show isdn active
