An organization has two PSTN gateways: one for US calls and one for UK calls. They want to route calls based on the number's country code. What should they configure?

Create a single voice routing policy with both gateways and let Teams choose the best one.

Assign each user a different phone number range.

Create two voice routing policies, each with a route that uses the appropriate gateway and a pattern that matches the country code.

Configure the SBCs to route based on the caller's location.

Your organization has two SBCs in an active-active configuration for Direct Routing. You want to ensure that if one SBC fails, calls are automatically routed to the other. You have created two PSTN gateways and a voice route that includes both gateways. What else must you configure to achieve automatic failover?

Set the 'Priority' value on each PSTN gateway in the voice route to define the order of failover.

Enable 'Failover' on the PSTN gateway settings.

Configure the SBCs to use a shared IP address for failover.

Assign both PSTN gateways to the user's voice routing policy.

An organization is setting up Direct Routing. They have an SBC that is already used for another SIP trunk. They want to use the same SBC for Teams. What is the first step?

Create a new PSTN gateway in the Teams admin center using a new FQDN that points to the SBC.

Assign Teams licenses to all users.

Disable the existing SIP trunk on the SBC.

Ensure the SBC has a public certificate and is reachable from the internet.

You are creating a PSTN gateway for Direct Routing. Your SBC has a certificate with the subject name 'sbc.contoso.com'. What should you specify as the FQDN for the PSTN gateway?

sbc.contoso.com with a port number

You are configuring a new SBC for Direct Routing. The SBC is behind a firewall that performs NAT. You want to ensure that the SBC can receive SIP OPTIONS from Microsoft 365 and that responses are correctly routed. What is the best practice for NAT on the SBC?

Use a 1:1 NAT mapping from the public IP to the SBC's private IP.

Place the SBC in the DMZ with a public IP directly assigned.

Disable NAT on the firewall and use a private IP for the SBC.

Use port forwarding for TCP 5061 to the SBC's private IP.
