[SR-Users] uri parameter value case sensitiveness

[Daniel-Constantin Mierla]

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>

Cheers,
Daniel
