Skype for Business App SDK

Last modified: July 3, 2024

The Skype for Business App SDK has been retired and is not available for download and use. Instead, we recommend Azure Communication Services, where we will continue to invest our development resources.

Migrating to Azure Communication Services

Azure Communication Services is a cloud-based communications service that lets you add voice, video, chat, and telephony to your apps. ACS applications have the ability to join Teams meetings (as a guest), and we encourage implementers of the SfB App SDK to transition to Azure Communication Services. The ability to join Teams meetings as a guest using ACS is now available.

Azure SDKs that join Teams meetings

Azure Communication Services has multiple SDKs that can join Teams meetings listed below.

SDK Implementation Complexity Customization Ability Calling Chat
Core SDKs High High
Base Components Medium Medium
Open-Source Composite Low Low

More specific guidance for transitioning a SfB Mobile SDK implementation to ACS Meetings:

  1. Explore key ACS concepts:
  1. Create an Azure Communication Services resource in the Azure portal
  2. Allocate user access tokens
  3. Use the Calling SDK to implement chat and calling communication in your app. Samples are available to help get started.
