Abstract
A method, apparatus, and computer usable program product for transmitting intercepted VOIP data are provided in the illustrative embodiments. A VOIP call is intercepted in response to a lawful request for intercept by a law enforcement agency. VOIP data associated with the intercepted VOIP call is encrypted. The encryption may use a virtual private network an encryption using a key of a specific length, bit stuffing, or other encryption methods. The encrypted VOIP data is transmitted to the law enforcement agency using a public data network either during the VOIP call or after the VOIP call. The intercept request may be made during the VOIP call, or before the VOIP call. Furthermore, the VOIP data of the VOIP call may be stored before transmitting to the law enforcement agency, and archived based on archiving rules. The request for the intercept may be queued for processing according to queuing rules. Notifications based on the request for intercept, VOIP call characteristics, or characteristics of the VOIP data may be sent to one or more law enforcement agencies, and may also be encrypted.
