for some strange reason my posting ( 13th july ) has just
disappeared so i'm reposting cos i'm back to square one.
post from 13th july (simplified)

i'm using linksys router which connects to the internet
thru a non-UPnP symmetric NAT admistrator and i'm not
able to do voice at all on both windows/msn messenger it
says dis on my fren's comp when either one try to invite
for voice the network or computer you are trying to
reach is experiencing a problem please try again later
i've turned off my firewall .. task barpersonal
firewall disable .. what else amd i not doing right?

jonathan said to open router configuration and enable
UPnP can't remember exactly what else but anyway i called
up my cable company they seem ignorant of the UPnP and in
frustration the technician opened up all the ports on my
line he said it's still not too accessable to hackers cos
i'm using wireless so yes i was able to voice over msn
messenger but not windows messenger which was fine with
me then the next day my fren clicked on the whiteboard
button to invite me while we were conversing on msn
messenger and it knocked me off msn & when i reboot &
relog on i was back to square one with that every
irritaing the network or computer you are trying to
reach is experiencing a problem please try again later
so jonathan plzzzzzzzzzz get me back on msn voice again i
only managed to enjoy it for half a day what happened
with that white board invite? i've checked all my ports
are still open. is the router configuration for UPnP supp
to be on my pc ? i looked in there but don't see any such
button to enable .. helpppp
