Add domestic PSTN calling coverage to eligible Microsoft 365 Government Community Cloud users through a one-year subscription term. Microsoft 76C04BD29E3B-1Y provides the GCC US Domestic Calling Plan entitlement used with Teams Phone to support business calling to domestic US destinations. This subscription fits government and regulated organizations operating in the GCC environment that need calling-plan capacity rather than a collaboration or meeting service alone. It supplies domestic calling coverage for users who require a phone number and PSTN calling workflow within Microsoft Teams. Teams Phone capability and the underlying Microsoft 365 user licensing remain separate licensing considerations. The defining attribute of this offer is its GCC US scope and annual term. It is a domestic calling plan, not an international calling plan, conferencing add-on, physical phone, or software download. Use it when the requirement is a one-year entitlement for US domestic calling in a GCC tenant, with the appropriate Teams Phone and user licenses assigned to the calling user.
