While in a call, add another person to the call
Reopening previous UserVoice post per request of MS Support:
https://microsoftteams.uservoice.com/forums/555103-public/suggestions/16952083-while-in-a-call-add-another-person-to-the-call
"While in a call, you should be able to add another person (or more than one) to the call, to instantly create a group call. Similar as in Skype by clicking the "+" button."
This is NOT completed - this feature, as well as various other features (such as Delegate Call-As) are not available in PSTN calling/Calls tab, only Teams-to-Teams calling (via the Chat tab).
These features have been marked as completed in the UserVoice as well as the roadmap but that is not correct.

I concur with Jon, this has not been implemented. Surely Teams should be able to implement a simple request that add a third person to a 1:1 call? One would expect this to be a standard feature?

This has NOT been implemented. The feature is available from a teams MEETING but unavailable is a private 1:1 call.
User experience: In an adhoc 1:1 call and then desire to add a user to the call. Curent necessary action: Hang up call, create a meeting.
Desired action: Ability to add users to 1:1 call, and/or perhaps convert 1:1 private call to a meeting? -

This feature is already implemented, I just tested it and added an external number to an existing call.

This does work. Can call an external mobile number then add another external number to the call.

How about merge calls functionality in addition? Skype for Business had "merge call", but in Teams everyone already on the call has to hear the whole process of dialing out to the other person. Not optimal.

Confirming as well that this is now present 👍

Heads up that this is now available... Just click the little person with the + in the top right of the window while on a call.

This is badly needed for PSTN calls. I needed this for the first time and could not believe that simple 3-way PSTN calling wasn't implemented. I'm hesitant to ever call anyone on Teams now because I always need this feature.
We had to all of our accounts back to Islands from Teams-only because of this.
The original 400+ vote request for this shouldn't have been closed until this was implemented for PSTN calls as well.

Curious, I just used this feature yesterday and it worked for me. Added a new user to the call I was already in.
