Hi Adam,
Thank you for your mail. So I propose the following text then:

The appearance of the Reason header is applicable to final responses
      3xx, 4xx, 5xx and 6xx and in addition for 199 Responses as defined within
      ietf-sipcore-199.txt. Also the Reason header is
      applicable to provisional responses18x which are generated by an
      interworking gateway from ISUP to SIP.</t>

Best Beagards

Roland

Given that RFC 3398 specifies the generation of a 301 in response to a 
cause code of 22 under certain circumstances, it seems pretty 
appropriate to allow the inclusion of a Q.850 cause code in 300-class 
responses also. Or, at least, as appropriate as it would be to include 
them in 4xx, 5xx, and 6xx responses.
