•------------ Summary --------------

Input file: faxpassthru.cap

<00.723>: (G723) 2.213:10000 => 2.116:10002

total 38 pkts(70 frames), lost 0 pkts, fill 7 silence pkts

This indicates that the input filename is faxpassthru.cap. The output file 00.723 contains the G.723-compressed stream from <2.123:10000> to <2.116:10002>; 38 packets (70 frames) were processed by rtpcatch. No lost packets were detected and seven silence packets were found.

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.
