Removing parameters form contact and other headers of an INVITE message

Hello!

I'm working on an access scenario and everytime I want to place a call, I get a 400 bad request
Taking a look at the trace, I can see this parameter: Proxy-Require: com.nortelnetworks.firewall in
several places of the INVITE, including the contact header and some weird header names as x-nt-location


I tried to make an HMR to strip the parameter:



 name                           test_require
        description
        split-headers
        join-headers
        header-rule
                name                           require
                header-name                    Contact
                action                         find-replace-all
                comparison-type                pattern-rule
                msg-type                       any
                methods
                match-value                    Require:.*\R
                new-value
                element-rule
                        name                           strip
                        parameter-name
                        type                           header-value <---- NO SURE IF THIS IS THE RIGHT VALUE
                        action                         find-replace-all
