Do you mean Diversion header, that which is based on levy draft http://tools.ietf.org/id/draft-levy-sip-diversion-08.txt ? I don't know if Diversion must be set before a response of "Moved Temporarily" or another msg., or if our sip proxy knowing about the forwarding situation must attempt to send the invite with diversion already included... Examples here (posted by Brett Tate) http://tools.ietf.org/html/draft-ietf-sipping-service-examples-15#page-76 are using "181 Call is being forwarded" as if the proxy sip was a user agent but explains that the forwarding could be accomplished using redirect "302 Moved Temporarily" response.. Seem to be many options, but don't know what is recommended..or which is absolutely not recommended.
