GNU Radio and VoIP Processing


#1

Did anyone try to use the GNU Radio framework for VoIP processing? e.g.

  • receiving an RTP stream via Ethernet port as an input
  • sending an RTP stream via Ethernet port as the output
  • RTCP support
  • implementing voice codecs (G.711 A/u…)
  • voice activity detection (silence removal and comfort noise
    generation)
  • RFC2833 implementation
  • sRTP support
  • 3-party conferencing
  • voice/music file playout as an RTP stream
  • telephony tone generation & DTMF detection
