Zusammenfassung:	A method and system for handling audio packets in a VoLTE call by a User Equipment (UE) when ROHC is enabled is provided. The TCP/IP layer provides the VoLTE call properties to the ROHC compressor. The TCP/IP layer receives the audio packets from audio engine and sends the RTP packets directly to ROHC compressor. Further, the ROHC compressor compresses the IP/UDP headers and RTP header. The ROHC compressor sends the compressed RTP data along with payload to the network in the UpLink data path. During DownLink data path, ROHC decompressor receives compressed ROHC packet from network. The ROHC decompressor ignores the construction of IP/UDP headers for compressed data. The ROHC decompressor constructs RTP header and RTP payload and sends the RTP header and RTP payload to the TCP/IP layer. The TCP/IP layer ignores validation of IP/UDP headers and sends the RTP packets to audio engine. FIG. 4
