UA should ignore unexpected headers in the response.
As UA is the final destination it of no use in removing it.  But still you 
should never remove a Header but should ignore (Proxy, UA....) it unless there 
is reason for that .

Subject: [Sip-implementors] Query regarding the handling of Resource-Priority 
header

Hi

I have a query regarding the handling of Resource-Priority header in SIP 
messages.

RFC 4412 says that the header should only come in Request messages. As per 
Section 20 of RFC 3261, any header or extension which is unknown must be 
"ignored".

We have a UA which understands Resource-Priority header (it is a known header). 
If it receives a  Resource-Priority header in a response, what should be the 
expected behavior:

-          Whether the UA should remove the header from the response?

-          Or the UA should simple ignore  the header and not remove it?



Thanks
Rakshit
