You have a Microsoft Teams Phone deployment.
You plan to implement outbound calling restrictions to meet the following requirements:
Users cannot dial out during a Teams conference call.
Users can make outbound PSTN calls to international and domestic numbers.
You run the following PowerShell command to configure the outbound calling restrictions.

Which policy should you use for the <policyName> variable?
Select only one answer.
A. DialoutCPCandPSTNDisabled
B. DialoutCPCDisabledPSTNDomestic
C. DialoutCPCDisabledPSTNInternational
D. DialoutCPCZoneAPSTNDisabled
Answer
To implement outbound calling restrictions in Microsoft Teams that prevent conference dial-out while allowing international/domestic PSTN calls, use DialoutCPCDisabledPSTNInternational (Option C).
C. DialoutCPCDisabledPSTNInternational
Explanation
As an administrator, you can use outbound call controls to restrict the type of audio conferencing and end-user PSTN calls that can be made by the users in your organization.
Outbound call controls can be applied on a per-user basis or on a per-tenant basis. The DialoutCPCDisabledPSTNInternational cmdlet ensures that users in the conference cannot dial out but can make outbound calls to international and domestic numbers.
Policy Structure
Microsoft Teams policies follow DialoutCPC[ConferenceSetting]PSTN[PSTNSetting] naming:
- CPC = Conference dial-out restrictions
- PSTN = End-user outbound calling permissions
Requirements Match
- Conference dial-out disabled: CPCDisabled ensures users can’t dial out during meetings.
- PSTN calls allowed: PSTNInternational permits international/domestic outbound calls.
Implementation
Use the command:
Grant-CsDialoutPolicy -PolicyName DialoutCPCDisabledPSTNInternational -Global
This applies the policy tenant-wide, ensuring all users inherit these restrictions unless overridden.
Why Other Options Fail
A (DialoutCPCandPSTNDisabled): Blocks both conference and PSTN calls.
B (DialoutCPCDisabledPSTNDomestic): Restricts PSTN calls to domestic only.
D (DialoutCPCZoneAPSTNDisabled): Limits conference dial-out to Zone A countries and blocks PSTN.
This configuration aligns with Microsoft’s documentation for granular call control in Teams Phone deployments.
