Jonathan In the 100rel spec (03 version), it is said that the Route headers constructed from a reliable provisional response MUST only be used for the PRACK and not for any subsequent messages. Why is this so? The Record route on the final response from a UAS leg cannot change from the Record route sent in a reliable provisional response. So, if the Record Routes are saved against corresponding legs, there is no need for this rule. Thus, it would be useful to save and use this route for subsequent requests to the same uas leg(CANCEL, COMET, BYE whatever). The record route saved by a uac against a particular uas leg in the call cannot change, or can it?
