I think The problem is that both UAS and UAC must have > the same system time to generate a useful result.

The request can contain a header like: TimeStamp: 25 and the proxy/server replies in the 100 Trying: TimeStamp: 25 0.001 This means that it has token 0.001 seconds to the server in order to process the request and generate the 100 response. -- Iñaki Baz Castillo <[email protected]> -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Kamailio (OpenSER) - Users mailing list [email protected] http://lists.kamailio.org/cgi-bin/mailman/listinfo/users http://lists.openser-project.org/cgi-bin/mailman/listinfo/users
