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".
