MediaProxy (if it well configured) should work in that case. In case caller and called behind the same call, you explicitely **need** to allow direct RP in openser.cfg by matching $si with $dd (if pulbic source address and destination address is the same don't apply SDP fix). But if you haven't configured it explicitely then maybe your conf is worng. -- Iñaki Baz Castillo ibc(a)in.ilimit.es _______________________________________________ Users mailing list Users(a)openser.org http://openser.org/cgi-bin/mailman/listinfo/users
