Hi, I have a scenario where I want a SIP client to be able to generate multiple redirect responses. The redirect responses will be generated based on user actions and will have a variable delay between them. As far as I can see there is no standard's compliant way to achieve that since the first

I got queried about this when an interop problem popped up. I know what I think the right answer is, but want to check what others think. Here is the case: Alice calls Bob: INVITE ... From: ;tag=;foo=bar this succeeds and a dialog is established. Then, within that dialog, Bob sends a
