Bulk Voice Traffic Simulation

RTP core can generate and receive voice traffic over IP networks and can work with applications such as GL’s MAPS™, VQuad™, and RTP ToolBox™ (PKS102). Transmit and Receive pre-recorded Voice Files in  wave, pcm, and GL's proprietary pre-compressed GLW files with a synchronous Tx/Rx option.  You can also directly send live voice using Talk using Microphone feature, and play the recorded voice files directly on to PC speakers. Some additional features that help in the voice traffic simulation are listed below-

• Allows to specify a desired voice payload type to each codec for sending and receiving payload;
• Sampling rate of the codec is displayed for the selected codec.
• Comfort noise generation is supported for A-law, µ-law and G.726 codecs for sending and receiving payload.
• Allows to set the buffer used for delayed packets that arrive at receiving end (both static and dynamic jitter buffers are supported)
• Allows to set QoS (Type of Service) properties such as precedence, delay, throughput and reliability values to the outgoing stream
• Comprehensive voice codec support -

• G.711 (A-law / Mu-law - 64kbps)
