Was more for my second example: allowing same RTP ports for all UA which 
are not the well known for each application.

Treat me as stupid ;-) No, joking :-) Does it mean that I can safely 
remove the gnomemeeting entry from Gconf?

Ok, agree. But how you want to explain to people they have to open some 
ports on there firewall if you don't know which one ;-)? Also, the range 
is always too large for me (security reason), especialy if you want to 
implement in professional areas and you have to ask the computer 
administrator to open 1000 ports on there firewall just for 1 or 2 VoIP 
devices!

I vote for a possibility to have RTP ports in preferences, even 1720 and 
5060 ports should be possible to modify: if providers are blocking those 
ports, it's easier to modify in an application that to setup firewall 
rules (user side).

What's the difference for you about RTP and UDP? From what I saw, my 
audio went through 5065 which are marked UDP. Are RTP range only for H323?

Thanks to share your knowledge with us ;-)
