Is it possible to automate a Teams call to a landline, ask user a question and collect answer with his keypad?

Here is a full description of our needs :

1) collect a employees phone numbers from an excel or sharepoint list
2) call them one by one, play recorded message offering them to accept or decline with the dialpad
3) collect answers and stop calling people when the target is achieved
4) save the results in a new column

I googled but step 2 seems to have no online guide. Leading me to think Power Automate cannot do this at all?

Hi @Volt26,

You can do this pretty quickly with a Twilio account. And it's pretty cheap and easy to do. I use it for text messaging but voice is also an option. If you are pinging employees, a send email with options is even easier, give them a button to push in an email (super simply in power automate). That said, yes, voice, text, and/or email with options all work (but not directly with Teams).

Hi Volt26,

Thank your for choosing Power Platform Community.

Here’s a streamlined summary of a possible solution.

Automated Calling with DTMF (Dual Tone Multi Frequency) Input

To achieve outbound calls to landlines, play recorded messages, and collect dialpad responses, Power Automate alone isn’t enough. You'll need a hybrid setup:

What Power Automate Can Do
Retrieve employee numbers from Excel or SharePoint

Update response results back into those sources

Orchestrate stop conditions (e.g., once enough acceptances are received)

What Power Automate Cannot Do
Call PSTN numbers directly

Play audio during a call

Collect keypad input (DTMF)

Recommended Tools

Telephony and keypad input - Twilio or Azure Communication Services
Workflow and data handling - Power Automate
Data source SharePoint list or Excel sheet

This setup gives you an IVR-like experience with scalable automation and response tracking.

If this fixes the issue, please mark as resolved to help others with find it.

Happy to help
