A list shows all connections with client and server IP addresses and ports. The RTP payload type is shown as well as timing information and counters, jitter and MOS values and SSRC (synchronization source) of both client and server. The min and max audio levels (decibel relative to full scale, dBFS) per direction are shown if G.711 A-Law or μ-Law is used. For calculation, raw A-Law or μ-Law values are converted to 16 bit PCM values. Those values are then converted to dbFS: | A list shows all connections with client and server IP addresses and ports.

Graphs per connection can show packets, packet loss and packet duplication, bit rate, jitter, MOS and the max audio level of client and server over time. A PCAP button allows for PCAP capturing. If a proper codec is used, audio capture buttons for both directions are available allowing downloads in MP3 format. Following codecs are supported for audio extraction: | Graphs per connection can show packets, packet loss and packet duplication, bit rate, jitter, packet time delta, MOS and the max audio level of client and server over time.
