Privacy: id chaning From header
I am looking at messages where it seems like the privacy: id header is changing the From header when leaving the trusted side of our SBC. I'm just trying to figure out if this is 1) a default behavior 2) is there a way to supress this behavior other than maybe deleting the privacy header or modifying with an HMR?
