We can extend the rules action part to include this one of requesting a certain header to be added since it can indeed be useful. But the one with formatting the to or from header in a certain way is quite hard to express as a rule.. regards, Anca > Thanks! > -Brett > > ------------------------------------------------------------------------ > > _______________________________________________ > Users mailing list > [email protected] > http://lists.opensips.org/cgi-bin/mailman/listinfo/users > _______________________________________________ Users mailing list [email protected] http://lists.opensips.org/cgi-bin/mailman/listinfo/users
