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".
