Can anyone guide me or give me suggestion to achieve compression of media packets in opensips or rtpproxy? I have referred LZ77 , LZW , Huffman , ROHC algorithm for compression. Is there any specific file that can compress RTP packets in opensips or rtpproxy? Is there any library file that can be used in linphone to achieve media compression?</span><div>

It can remove 40 Bytes (IP Header 12 bytes + UDP header 8 Bytes + RTP Header 12 Bytes) of overhead and compress 40 bytes to 2-3 bytes. So rtp will send only 2-3 bytes of header plus 20 bytes of payload.</span></div>
