sipXproxy and sipXregistrar both have plugin architectures. Question is, would they have a list of the gateways to identify and would they be allowed to modify the SIP message which I believe you need. Outside that, fronting the sipXproxy with another proxy like opensips, kamailio, openser, opensbc... might be another option. _______________________________________________ sipx-dev mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-dev/
