GCC High CallTower’s Microsoft Teams Phone & Audio Conferencing Services Hosted In GCC High


CallTower’s Direct Routing for GCC High is designed to meet the unique requirements of Microsoft 365 Tenants hosted in GCC High, including:

  • PSTN geo-redundancy
  • End-to-end encryption
  • Audio conferencing
  • Dial-in DIDs

This includes residency in Azure Government, full US data sovereignty, and limited integration with third parties. CallTower provides a fully hosted solution enabling voice for GCC High with Teams Audio Conferencing.


Microsoft GCC High Features

Microsoft GCC High includes many of the same feature sets and products as the commercially available Microsoft 365, such as:

  • Microsoft Teams
  • Exchange Online
  • OneDrive for Business

Addressing Workplace Challenges

With the global pandemic and evolving workplace needs, companies demand collaborative voice and audio-conferencing options within GCC High solutions. Microsoft does not offer PSTN access directly, which must be added via direct routing. CallTower helps organizations fill this gap with voice options for Microsoft 365 GCC High services.


Set Up via CallTower Teams Connector App

The CallTower Teams Voice Connector app allows CallTower to provision MS Teams services for customers. Steps include:

  1. Sign in with a Global Administrator account.
  2. Review and accept permissions requested by the app.
  3. Assign the “Teams Telephony Administrator” role to the app via Microsoft Entra admin.

Benefits of CallTower’s Solution

With CallTower’s Direct Routing telephony and Microsoft 365 GCC High security, clients can:

  • Facilitate dial-in conferencing and PSTN calling through Microsoft Teams.
  • Accelerate adoption of Teams in GCC High organizations.
  • Simplify migration to Microsoft 365 GCC High.

If your company requires a secure GCC High environment or already operates within GCC High, CallTower can deliver voice and telephony solutions to enhance connectivity and collaboration.
