How to add something to the CLID?

Hi folks,

I am trying to add something to Remote-Party-ID, e.g. the original message is

Remote-Party-ID: "Test Device1" <sip:8471@192.168.100.10>;party=calling;id-type=subscriber;privacy=off;screen=yes

So the called party would see "Test Device1" when getting the call.

How can I add "Company:" in front of "Test Device1", so that the called party would see "Company: Test Device1"?
