7960 plus soft phone using the same DN

I would like to have a 7960 cisco phone and x-lite softphone share a DN. I also would like the 2 to ring at the same time. I currently have them setup where they are registered but when I call them I am only able to get one to ring. Whichever phone was the most recent to register is the one that rings. Is there any way to get both to ring at the same time?

I read about the Hint command in place of a priority # is this the correct way to go? If so I wasn’t able to get it to work so any examples would be appreciated.

Thanks!
