For your example, ASP1 can reply with ERR -maybe with ERR("No Configured AS for ASP" or with ERR("Invalid Routing Context")- -actually ASPIA, or ASPIA-ACK may be a better choice but I doubt this is defined somewhere in the specification-. > > Thank you > > ________ > | | > | User 2 | > |________| > X | > ___|____ ____|___ > | | | | > | AS1 | | AS2 | > | PC = X | | PC = Y | > |________| |________| > | | > ___|____ ____|___ > | | | | > | ASP1 | | ASP2 | > |________| |________| > | | > |_________________________| > > > > > ______________________________________________ > Renovamos el Correo Yahoo! > Nuevos servicios, más seguridad > http://correo.yahoo.es > > _______________________________________________ > Sigtran mailing list > [email protected] > https://www1.ietf.org/mailman/listinfo/sigtran >
