Thanks for this information, clear with
comparison. However, more
specific to what I am looking for:
If I add in INVITE:
Record-Route: <sip:1.2.3.4;abc=XYZ>
Is allowed to the other party to set next header in BYE?
Route: <sip:1.2.3.4;abc=xyz>
my interpretation is that that is allowed,
because abc=xyz is uri
parameter and "comparison of all other components of the URI
is case-insensitive unless explicitly defined otherwise".
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.
Cheers,
Daniel
