LRT - arbitrary key lookup and policy-attribute

@PAI2

Hello!

I construct a custom, hidden header from 'From' and PAI headers using HMRs. It is called @PAI2. It has a standard URI format. The '@' sign indicates that this header must be deleted on outbound side.

Now... how can I reference this header in a local-policy? If I use lrt:some-name;key=$PAI2 the debug log says 'key not found'. If I use lrt:some-name;key=@PAI2, the SBC searches on the entire header and lrt:some-name;key=$@PAI2 is not acceptable by ACLI.

Any idea?

Thanks!
