RE: [Sipping-tispan] Requirements 02e

Roland,

In case of diverted communication, the To header retains its original value. 

In any case, (in my mind at least) a callee accepting a call would add this information (header or parameter) to the 2xx response (e.g. to INVITE), so the caller would get information provided by the UA that is answering, not always the one that he originally called. 

If this was not intended, then perhaps this is something to clarify in the requirements. But whether a header or a parameter would be used, I don't think there's a difference w.r.t. the issue you mention

Regards,

Jeroen
