The easiest choice for telecommunication operators

Extensible Workflow System (EWS) is the information system to fulfill Telecommunication operators requirements to handleLaw Enforcement Agency (LEA) data requests, like traffic data, voice interception, customer data from phone numbers and many more.

The system receives requests from LEAs, allows to generate tasks for specific and configurable departments within or without the company. When all information is retrieved, it generates responses to requesting LEAs, sends them and securely deletes sensitive data only -as it leaves all data for invoicing. All that in a secure and extensible environment. The invoicing module completes the process in compliance with LEAs billing requirements. An extended filtering of which activites to invoice provides the invoice total amount of the filtered activities, also by LEA.
