Hi Pavan, There can be three reasons, as much I know to user part unavailabilty: 1.User Unknown 2.User Uenequipped 3.User Inacessible. According to you for case 1 ASP can generate Error Message and reply with error code as "INVALID ROUTING CONTEXT" and will drop the recved msg. But in RFC 3332, I was not able to undstd how the other two cases will be handled at ASP, I think its not defined in RFC. Any feedbacks. Regards, Kuldeep C-DOT India.
