The output is printed on screen and saved in the file file.sum.
The following lines are described:
• [ 25]open file: 00.723, (G723) 2.213:10000 => 2.116:10002
This indicates that rtpcatch reached NAI Sniffer packet number 25 and opened a new file named
00.723 to store an audio stream consisting of G.723-compressed data. The audio path originates
from the IP address ending with 2.213 and port 10000 (written as <2.213:1000>) and terminates at
the IP address ending with 2.116 and port 10002.
• [ 29] <00> 1 silence pkts from TS 1760 (seq# 3)
This indicates that rtpcatch detected one silence RTP packet in the audio path <00> and the silence
packet began at timestamp 1760. This occurred at packet number 29 with the RTP sequence number
3.
• [ 106] <02> 2 lost pkts from seq# 39
