However, i have problem if i would like to extend the configuration with
topology hiding functionality - byusing the B2B modules.
By calling the scenario with b2b_init_request("top hiding"), Opensips fires
out the INVITE with wrong SDP Connection information (IP of calling UA)
towards the called party.
Yes, indeed the B2BUA generates a new request and the changes made on
the old request are not visible in the new one. You could change that
request in local_route before being fired on the network, but then you
have problems with the generated replies.. there is no way to catch
those before being sent out.
So the only solution is to introduce another hop before sending the
request out - you could either loop the generated request or run b2bua
in another instance of opensips. In both cases the b2bua should be the
first to do the processing and the on the other hop do the specific
changes on the message.
