Merge an incoming call with current call

[Jim 777]

I'm in hurry (kids Birthday party and I'm here instead) but i did dial a number that I didn't mean to and when I noticed, I hit the back button out of habit. Then I hit the intended contact. It never stopped the first call next thing I knew, it said "merging calls"

I think that was setting up a 3-way that I initiated.

Now, if only the wife would go for that!
