It was my pleasure to meet all you guys ... I am hooked now. In my
mind I have a background process trying to figure out how to go to the
next one (San Diego? :D )

Ok ... i think is a parameter in force_rtp_proxy, right?

in this ser.cfg ... the force_rtp_proxy() call will automatically
change whatever is needed in the SDP, won't it? so no nat stuff
checking functions ... cool :)

I think i will do so ... I deleted vmware a while ago in favour of
having colinux on my windows laptop ... but i cannot run various
colinuxes (i think ... ) on the same box ...


A final question ... basically thinking out loud (and writing it down) :)
I read that rtpproxy won't start relaying until it got an rtp packet
from both sides ... is it true? could this not cause problems,
specially with chained rtpproxies, if say, i have one of the phones
not sending rtp packets (say, it starts muted ... muted means no rtp
packets)?
