Wow, I thought I was being very clear about what I'm talking about.
Yes, I'm talking about 3-way calling but only after the first call is in progress. I'd like to know how to merge a second incoming call into the existing call to make it a 3-way call. NOT as the dialer to both of the other parties.
Now you can call Jack, then call Jill, then merge the conversation. That does work.

Yes, this works as documented but doesn't solve my issue :-\
...You're on the phone talking with Jack. Jill calls. You answer Jill ....
