Shared Calling for Microsoft Teams Premium

Transform Your Calling Experience

Microsoft Teams Shared Calling, part of the Teams Premium package, allows organizations to use shared phone numbers for placing and receiving calls. Instead of assigning individual Public Switched Telephone Network (PSTN) numbers to every user, centralized resources can be shared.

This is especially useful for:

  • Reception desks
  • Customer service teams
  • Help desks
  • Collaborative workspaces

Benefits

  • Reduced Administrative Overhead: Simplify management with shared resources.
  • Flexible & Reliable: Provide a seamless calling experience for your team.

CallTower, a Microsoft Solutions Partner with Modern Work Designation, delivers cloud-native solutions that integrate seamlessly into your existing ecosystem.


Why Choose CallTower?

By selecting CallTower, you gain access to a Microsoft-certified solution designed for scalability. CallTower enhances the Shared Calling experience with:

  • Centralized Call Routing: Simplify call management.
  • Extension Dialing: Easy internal communication.
  • Expert Support: Backed by industry-leading voice expertise.

Key Features

1. Seamless Connectivity

  • Make and receive both internal and external calls using centrally managed resources.

2. Auto Attendants

  • Simplify inbound call routing by linking shared resource accounts to automated attendants.

3. Emergency Calling Support

  • Ensure team safety with enterprise-grade emergency calling capabilities.

4. Streamlined Compliance

  • Maintain regulatory adherence with centrally managed voice routing policies.
  • Reuse resource accounts across multiple Shared Calling policies for maximum efficiency.

Emergency Calling Configuration

Important Notes

  • Properly configure emergency numbers and locations to ensure compliance and safety.
  • Microsoft Teams dynamically determines user locations during emergency calls (when supported by your network infrastructure).
  • Emergency routing behavior depends on:
    • Service number type
    • Underlying calling configuration

Limitations

Toll-free numbers require additional subscriber numbers for emergency callbacks.

Shared Calling is not supported in certain countries, including Romania, Singapore, and Japan.
