[Devel] how to alter the ACK to a 487

[Bogdan-Andrei Iancu]

of course, is each one's decision about his service requirements. For 
that purpose I find more appropriate the usage of hdrs la RPID or 
Diversion. Billing information should not force specific formatting of 
headers involved in SIP under-layer - like transaction layer.
