Learn the correct configuration step to enable SIP Gateway for SIP devices in Microsoft Teams, ensuring compatibility with calling policies for seamless integration.
Question
You have a Microsoft Teams Phone deployment.
You plan to use SIP devices to make and receive Teams calls.
You plan to implement SIP Gateway to connect the devices to Teams.
You need to enable SIP Gateway for the users in your organization.
What should you configure?
Select only one answer.
A. a calling policy
B. a dial plan
C. a voice routing policy
D. Operator Connect
Answer
To enable SIP Gateway for users in your organization and allow SIP devices to make/receive Microsoft Teams calls, you must configure a calling policy.
A. a calling policy
Explanation
SIP Gateway lets your organization use any compatible SIP devices with Teams to preserve your investment in SIP devices. Now you can sign in to Teams with your corporate credentials and make and receive calls with a compatible SIP device.
The calling policy in Microsoft Teams includes a specific setting (“SIP devices can be used for calls”) that authorizes SIP devices to connect via SIP Gateway. This setting is mandatory for integrating third-party SIP phones (e.g., Cisco, Poly, Yealink) with Teams.
Steps to Configure
- Access Teams Admin Center > Navigate to Voice > Calling policies.
- Edit the Global policy or create a custom policy, then enable “SIP devices can be used for calls”.
- Assign the policy to users requiring SIP device access.
Why Other Options Are Incorrect
Dial plan (B): Manages number normalization, not device connectivity.
Voice routing policy (C): Directs calls via Direct Routing/SBCs, unrelated to SIP Gateway activation.
Operator Connect (D): A PSTN connectivity method, not a configuration for SIP devices.
By enabling the SIP device option in the calling policy, you ensure compliance with Teams’ requirements for SIP Gateway integration, preserving legacy hardware investments while leveraging Teams Phone functionality.
