hi,all experts i am new to H323.i have difficulty in understanding SessionID,i have refered to many readings. here are some questions: 1,according to H245,SessionID is a unique RTP or T120 session identifier in the conference. does it mean each sessionID is unique in the conference. 2,i assume seesionID is unique,H245 also says audio session number is 1,video session number is 2, so in a multipoint conference,are all of audio session numbers equal to 1? if so,the conclusion 1 is not right. 3,are the session number 1,2,3 implied assigned by Master? 4,if i leave the sessionID blank,will it be a serious error? thank you advanced!
