Phone call sample

Shows how to use the Calls APIs. This sample does not follow the typical sample template pattern, it is a sample app that uses the MWC pattern to give you a working E2E phone call application to start with.

Note: This sample is part of a large collection of UWP feature samples. If you are unfamiliar with Git and GitHub, you can download the entire collection as a ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

Note: This is a mobile only sample.

This sample allows the user to:

• Query phone line information
• Query phone call status
• Query voice mail information
• Place phone calls (Single and Multi-SIM)

The app UI represents the following tabs:

Status tab

This focuses on accessing basic phone line information.

Contacts tab

This focuses on contacts integration with your own phone call app.

Dialer tab

This is a dialer that allows users to place a phone call.

Voice mail tab

This focuses on accessing voice mail information and placing calls to the user's voice mail.
