VoIP Bulk Call Generator

Important Enhancement Introduced to PacketGen™:

  • High-Density Performance (2000 Simultaneous Calls)
    PacketGen™ on an i7 PC can now support 2000 simultaneous calls with both SIP and RTP generation. This performance is with a G.711 codec, while other codecs may provide higher call densities.
    The distributed architecture of PacketGen™ allows achieving higher call rates and media streams, and provides greater scalability i.e. easy to add additional load generation capacity.
  • Support for Additional Codecs
    Additional codecs GSM-HR (Half Rate) and GSM-EFR (Enhanced Full Rate) are now supported.
  • Support for Multiple Frame Interval (Packetization Time - "ptime")
    All supported codecs can operate with frame interval in multiples of minimum frame interval supported for the codec. For example minimum frame interval for AMR/AMR-WB is 20 msec, now we can operate with ptime like 40, 60, 80 msec.

  • Option to Enable or Disable VAD (Voice Activity Detection)
    Provides option to enable or disable VAD for all VAD supporting codecs such as AMR, AMR-WB, HR and EFR. 

  • Handles Media Re-Negotiation.
    Calls support media re-negotiation and are updated with media parameter changes like codec, port indicated during Re-INVITE or during call Off-Hold.

  • Supports REFER, NOTIFY and INFO Methods
    Now calls can process REFER, NOTIFY and INFO methods during call and are replied with 200 OK responses.
