Patent ID: 8787381

Claim:
A wireless communications device, comprising: an application processor (AP) configured to execute a protocol stack, including at least one of: a session setup protocol, a media carrier protocol, a transport protocol, and an Internet Protocol (IP) of an IP stack; and a processor, located outside of the AP, configured to implement an audio sniffer module, wherein the audio sniffer module is configured to receive a first IP packet and to determine whether or not the first IP packet contains a first audio frame, the audio sniffer module further configured, if the first IP packet does not contain the first audio frame, to forward the first IP packet to the AP, and, if the first IP packet contains the first audio frame, to extract the first audio frame from the first IP packet and to forward the first audio frame to an audio processor, and wherein the audio sniffer module is further configured to receive a second audio frame from the audio processor; encapsulate the second audio frame in a first transport protocol packet and insert a predefined transport protocol port number; encapsulate the first transport protocol packet in a second IP packet and insert a predetermined destination IP address; and forward the second IP packet to a transmitter module of the wireless communications device.
