Gentlemen, 

I have to excuse myself indeed as indeed it was a codec only problem.

Party one was a windows98 user where G711 is in the codec list of netmeeting. 
That one was negotiated with my gnomemeeting.

Party two was a windows xp user where G711 is apparently not in the codec list 
of netmeeting ... As also MS-GSM was not there , audio could not be 
established.

Installing your MS-GSM , well the one from your download page , made the thing 
working. Not that I'm enthousiastic though about audio quality ...

Some related questions for the problem :
 -> How to get G711 on netmeeting in windows xp ? (maybe too offtopic ...)
 -> How to get the SpeexNarrow-15k on windows ? For your reference, I managed 
to get the Speex codec from openacm.org into windows netmeeting , at least it 
displays in the netmeeting audio. But the codec seems not to match with the 
one in gnomemeeting ? It has numerous modes 8..32KHZ Q1-Q8 ... which one does 
in fact match , if at all , with the gnomemeeting one ?
  -> Is there an other way than gnomemeeting --debug=2 to find out the 
negotiated codec ?

Thanks a lot for your help !
