Phenomenon and Questions  Listen some quarrel voice  Ethereal cannot catch packet  Some action cannot run (previous slides that mark “*”) 18

SJPhone Bugs  Occur when two softphones in the same PC SJPhone calls to X-Lite when SJPhone hangs up phone  Via part didn’t have branch X-Lite calls to SJPhone  c part in SDP (c : IN IPv ) 19
