Question

You have a Teams Phone deployment that contains two sites named Site1 and Site2. Each site has a Session Border Controller (SBC). You have a user named User1. User1 relocates from Site1 to Site2 and is assigned a new phone number. You need to change a policy assigned to User1 to ensure that the SBC at Site2 is used when the user makes outbound calls. What should you change?

Why each option

The voice routing policy controls which PSTN usages and routes - and therefore which SBC - are used for outbound calls, making it the correct policy to update when a user moves sites.

Athe calling policy

The calling policy controls features like private calling, call forwarding options, and voicemail, but does not determine which SBC or route is used for outbound PSTN calls.

Bthe voice routing policyCorrect

A voice routing policy links to PSTN usages that reference voice routes, and each voice route specifies an SBC gateway. By assigning User1 a voice routing policy scoped to Site2's routes, outbound calls will be sent through the SBC at Site2 rather than Site1.

Cthe caller ID policy

The caller ID policy controls what number is displayed as the outbound caller ID and has no bearing on SBC or route selection.

Dthe dial plan

A dial plan normalizes dialed number formats into E.164, but does not influence which SBC or PSTN route is selected for outbound calls.
