Hello, If a User agent Server or a Proxy server is authenticating an incoming reuest, say INVITE or register , Can the server send 100 trying before sending 401/407 Authentication required ? [Chris Boulton] Yes it can - to an INVITE request. 100 Trying is to be sent to stop the retransmission of INVITE requests . Suppose the server sends 401/407 first and after the authentication is successful sends 100 trying, will there not be retransmissions of INVITE requests ? [Chris Boulton] No - once a final response is sent the transaction is complete. The UAC would need to re-submit with a new transaction (new branch) containing Auth credentials.
