A Quick Summary of SS7
- CroSS7 is programmed to “know” which SS7 links and point codes to monitor.
- Once CroSS7 is programmed, it will monitor the network and capture SS7 messages associated with calls that are traveling on the LIS Trunk Groups.
- CroSS7 gathers SS7 messages and creates a Call Detail Record (CDR) which is then passed to the Automatic Message Accounting (AMA) System.
- CenturyLink uses these CDR’s to bill you, the CLEC, your MOU Charges.
- In addition, CenturyLink uses CDRs to validate your MOU billing to CenturyLink.
