Mogul Phone Calls

[DoooWeeeee]

I'm pretty much a noob with the mogul but I have a problem. Whenever I talk to someone on the phone and someone else calls and I push answer it still show the name of the person if your know what I'm talking about. I hate it when I press end and it end both of the calls the same time.
Do you guys know anyway to change this and let them show who you are talking to like a different calling interface or something and how to 3 way? Thanks.
