As abc is custom parameter, not something standard, I wonder how the UA
know if it is a case or not of an "explicitly defined otherwise".
I expected that UA has to take them and copy when they need to preserve
a value, such as Record-Route body becomes Route body.
Perhaps it is a case requiring lawyers and a judge for a final, obeying
decision -- or better I should ask on sip-implementors, hoping for one
of the SIP RFC authors to clarify it.
