Claim 10:
11. A method of processing, by a call processor, a Voice over Internet Protocol (VoIP) media call between a first entity and a second entity, the VoIP media call including separate signalling streams and media streams, and in which the media streams include first and second voice media streams over which media comprising audio information is transmitted between the first entity and the second entity without intervention by the call processor, the method comprising:
rerouting the first and second voice media streams so that the VoIP media call is redirected via the call processor, rerouting the first and second voice media streams including:
(i) creating a third media stream over which the media comprising audio information is to be transmitted from the first entity to the call processor, and a fourth media stream over which the media comprising audio information received by the call processor from the first entity via the third media stream is forwarded by the call processor to the second entity; and
(ii) creating a fifth media stream over which the media comprising audio information is to be transmitted from the second entity to the call processor, and a sixth media stream over which the media comprising audio information received by the call processor from the second entity via the fifth media stream is forwarded by the call processor to the first entity; and

using the call processor to modify the media comprising audio information received from the first entity, including the call processor removing sensitive audio information from the received audio information before the media comprising audio information is forwarded over the fourth media stream to the second entity.
