one click conference call dialing

I am a long time blackberry user and used to opening up my meeting invite/WebEx invite and clicking "Join Meeting" and the phone dials the telephone number + the conference code. I move to iPhone SE last month and it is very frustrating not having the feature on the iPhone. I have to first open the meeting invite, jot down the conference code on a paper, dial the telephone number and then enter the conference code. This can be so inconvenient when you are on the road and have back to back meetings.

can use help if somebody has figured out a way to make this work. Just dont tell me to purchase a third party app (that would be too easy).

Thanks
