Link analysis dialog box
This topic describes the purpose of the Link analysis dialog box, how to access it and all the settings and buttons on it.
This feature requires option E4 Phone data/analytics. If you do not have this option this screen is not available.
Overview
The Link analysis dialog box allows you to run a link analysis between two or more phone numbers. This analysis uses all the data you have uploaded including CDR files and phone data files and then provides you with all the connections between the phone users. The data included in the analysis is from:
- Calls and texts from the CDR files
- Calls and texts from the phone data files
- Email logs from the phone data files
- Instant messaging logs from the phone data files
- Other data sources from the phone data files such as instant messenger contacts, email contacts and Facebook friends.
This analysis is similar to the Common numbers analysis on the Call analyses tab, however the common numbers analysis only uses the data from the CDR files.
If you require information on running a link analysis refer to Running a link analysis.
