Patent abstract
Systems and methods of providing secure signaling for voice communications over a public switched voice network (PSTN) are described. The call signaling is received at a first secure voice signaling gateway (SVSG) in which it is encrypted utilizing a security key. The encrypted payload is tunneled from the first SVSG to a second SVSG at a destination network element. The destination SVSG decrypts the payload and passes it on to the destination. According to the invention the communication can be either masqueraded in which the address of the first SVSG is given as the origin or non-masqueraded in which the actual original of the voice communication is retained.
