Abstract

Monitoring calls in compliance with a law enforcement regulation or governmental law or order in a telecommunications network is provided. A law enforcement application executes commands that effect the law enforcement regulation. A primary rate interface (PRI) coupled to the law enforcement application redirects calls to be regulated by law enforcement regulation. A method for effecting a law enforcement regulation in a telecommunications network provides a law enforcement application is that regulates calls and a primary rate interface (PRI) for redirecting the calls to be regulated by law enforcement regulation.

Claims

an application for executing commands that effect the governmental regulation for monitoring the call; and

a primary rate interface (PRI) coupled to the application for redirecting calls to be monitored in compliance with governmental regulation.

2. The apparatus of claim 1, wherein the PRI carries any calling ID and called ID, such that there is no indication to a caller of a redirection of the call.

3. The apparatus of claim 1, wherein the governmental regulation is established by the Communications Assistance for Law Enforcement Act (CALEA).

4. The apparatus of claim 1, wherein the PRI includes a B-Channel that conveys voice signals and the PRI loops the voice signals to a termination point.

5. The apparatus of claim 1, wherein the PRI includes a D-Channel that conveys call data and the PRI forwards the call data to an operator.

6. The apparatus of claim 1, wherein the PRI is a personal computer (PC) card.

7. The apparatus of claim 1, further comprising a Service Control Point that determines whether a particular call is to be regulated.

8. The apparatus of claim 1, wherein the network is a public switched telephone network PSTN.

9. The apparatus of claim 1, wherein network is an Internet Protocol (IP) network.

10. A method for monitoring a call in compliance with a governmental regulation in a telecommunications network, comprising the steps of:

providing an application that regulates calls in compliance with the governmental regulation; and

providing a primary rate interface (PRI) for redirecting the calls to be regulated in accordance with the governmental regulation.

11. The method of claim 10, determining whether to regulate the calls based on a database.

12. The method of claim 10, redirecting voice signals over a B-Channel of the PRI.

13. The method of claim 10, redirecting call data over a D-Channel of the PRI.
