This integration allows Microsoft Teams users to call out via Yeastar PBX SIP trunks and offers a seamless unified calling experience for both Yeastar PBX and Teams users.

With the simple setup, Teams users can be associated with PBX extensions and call out directly on the Teams App using their PBX resources. Users can also benefit from the advanced PBX features and routing options that are not available in Teams, including IVR, call queue, call routing, and more—offering a cost-effective alternative to the Microsoft Teams phone license. The integration makes a complete unified communications & collaboration solution, enabling your team to work from anywhere.

Key Features

Make & handle calls. Make and receive calls directly from your Teams app and enjoy advanced PBX routing features time-condition, IVR, queue, ring groups, etc.

Use what you already have. No Teams-compatible handsets are required. Keep your existing phone number, SIP phones, and any SIP devices.

Cost saving. Save on SBC solution licensing. Eliminate costly Microsoft domestic or international calling plans. Choose your own cost-effective SIP provider in your region.

Connect Teams and non-Teams users. Teams users and PBX users can make free internal calls with PBX extension users regardless of location.
