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 the Internet Protocol, IP; and a processor, located outside of the AP, configured to implement an audio sniffer module; wherein the audio sniffer module is configured, in a downlink mode: to receive data bearer information from a radio frequency integrated circuit, RFIC, module of the wireless communications device; to receive a first IP packet and to determine based on the received data bearer information without IP filtering, whether or not the first IP packet contains a first audio frame that belongs to an audio stream, wherein the audio stream is identified by a source IP address and a transport protocol port number; if the first IP packet does not contain the first audio frame, to forward the first IP packet to the AP; 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, without using the AP, to an audio processor adapted to provide speech coding and acoustical processing functions, wherein the AP is entirely bypassed allowing the AP to enter a power saving mode during media over IP sessions; and the audio sniffer module is configured, without resort to the AP, in an uplink mode: to generate Real-time Transport Protocol, RTP, packets from digital audio data; and to encapsulate the RTP packets into transport protocol and into Internet protocol packets to enable Layer 2, L2, processing by the processor on resulting Voice over Internet Protocol, VoIP, packets before being forwarded to the RFIC module for transmission. 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 the Internet Protocol, IP;
