Klaus,
The linux box acts as a router, but only for the networks inside and not for
the internet since we are using non valid ip addresses for the internal lans
actually ive made it to work using 2 interfaces only the problem is the
third.
May be another solution will be using different domains for the interfaces
on the equipment ??
Thanks for your kind response.

Does the linux Box acts as router?
If not, you need rtpproxy in bridging mode.
Try to use openser's mhomed option:
# mhomed -- enable calculation of outbound interface; useful on
# multihomed servers.
mhomed=1
