DTNA packet size interval

Blueworx Voice Response always transmits RTP packets containing 20ms of audio (160 bytes). The additional MAC, IP, UDP and RTP headers mean that the actual packets size on the Ethernet are always 214 bytes.

Blueworx Voice Response does not implement silence suppression—packets are sent continuously regardless of the signal content.

For receive, Blueworx Voice Response accepts any packet size (even varying). However, the optimal size is 160 bytes (20ms).

Blueworx Voice Response Implements a ‘jitter buffer’ for received packets, which allows packets to be delayed or received out of sequence due to network loading without voice breakup. This implementation will also fill in ‘comfort silence’ if packets are found to be missing. This also allows the far end transmitter to implement silence suppression.
