A method and device are disclosed which receives packets streamed over a
packet network, decodes the packets received to generate a decoded signal
stream and filters the decoded signal stream to generate a pulse code
modulated (PCM) signal stream. The PCM signal stream may be tailored to
conform to the target destination transport requirements, including call
channels established over circuit-switched networks, whether wired or
wireless, without modifying the capabilities associated with the network
infrastructure or the client phone.
