Our users sometimes need to dial to an external number from the Teams app on their phone, add another external number to the call, then use the dial pad to navigate a phone tree. However, the Teams conference won't send the dialpad inputs to the phone tree system. Is there a way we can make this work?

@cgigate1460 and @Adam1982690, when I'm on a call, the dial pad in Teams -> Calls makes DTMF tones. I can use this to navigate prompts, enter information (e.g., PIN, zip code, meeting security code), or trigger effects in a multiparty conference call.
If you are saying that also works for you, but that you have a separate problem where DTMF tones stop working in the specific case where you want to add an additional party to an existing call, then you are correct that I was missing the point. If your issue ONLY occurs when making a call while already on a call, I admit I've never had a need to test that specific use case. If that's the issue, sorry for the confusion on my part.

This is not the scenario of the issue.
if you are talking about a pure phone call, you can use dial pad to dialout, you have DTMF tone to navigate through the phone tree (IVR).
The not working scenario, when you have a ongoing meeting (conference) , you want to add a participant to the meeting. the the wanted participant behind a phone extension or needs get through IVR tree to reach him/her, the Teams cannot send out DTMF tone to navigate through IVR. that is an issue

Slype for Business or Lync server don't have the issue.
SfB and Lync can merge phone calls and meetings together. Thanks to the SIP protocol, it can use re-invite to merge two or more sessions!
The issue is only in the Teams meeting!
Unfortunately, teams moved from the robust SIP protocols to the Skype protocol, which has very weak telephony features that causes huge problems for the telephony.

Im thinking the same thing. I found a React App that is a DTMF tone generator with dial pad buttons. I can put this into my own MS Teams App, but the audio currently goes to the users default sound device. Does anyone know how to send audio from a Teams app out to all participants? Without using a virtual audio device in windows piped to the microphone?

@RogerNorthupThe initial issue is about a 3-way call, I don't know how this tread changed subject.
When in a Teams 3-way phone call, the dial pad is unavailable.

@IT_admin_84 No, from what I can tell from the original post the dialpad is not unavailable. It is there, it is just not sending the inputs when navigating a phone tree. eg. When a call says "press 1 for this menu" while in a 3-way call, the user is going to the dial pad and dialling 1 and nothing is happening.
This is the same issue that many others are referring to in this thread.

My bad, the title says "when navigating a phone tree during a conference", I was implying that a conference is 3 people and more on call.
