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
This indicates that rtpcatch detected two lost RTP packets in the audio path <02>. The missing
packets began with sequence number 39. This occurred at packet number 106.

This indicates that the audio streams originating at <2.213> and <2.216> are G.723-compressed.
The audio stream from <2.116> was then up-sped to G.711µ-law at packet number 101. The NSE
signaling packets were sent at packet number 102, 103 and 105. Finally, the audio stream from
<2.113> was up-sped to G.711µ-law.
