ABSTRACT:
A network processing device identifies call requests that require secure media connections and that also require transport over both a packet switched network and a circuit switched network. The network processing device establishes an IP link over the circuit switched network and directs endpoints for the media connection to use Internet Protocol (IP) media encryption. The same IP encrypted media is then transported end-to-end over both the packet switched network and the IP link in the circuit switched network.
