Your organization uses Direct Routing and wants to ensure that calls to a specific emergency number are always routed to the SBC, even if the user is assigned a voice routing policy that does not include that route. What should you configure?

Configure the SBC to intercept all emergency calls before they reach Teams.

Set the PSTN gateway's 'Emergency calling' option to 'Enabled'.

Create a separate voice route for the emergency number and assign it to all users via a global voice routing policy.

Assign the user a separate emergency calling policy that overrides voice routing policies.

A company has Direct Routing configured. They have a voice routing policy that routes all calls to a single SBC. They are adding a second SBC for redundancy. They want to ensure that if the primary SBC is down, calls are routed to the secondary SBC. What is the best way to configure this?

Create a new voice routing policy for the secondary SBC and assign it to users.

Add the secondary SBC as a second gateway in the same voice route.

Use a DNS SRV record to point to both SBCs.

Configure the secondary SBC as a trunk on the primary SBC.

Which security setting on the SBC is required to ensure secure signaling with Teams Phone?

Enable TLS 1.2 and configure a certificate

Disable SRTP to reduce overhead

Use a shared secret for authentication

Allow all IP addresses on port 5061

Contoso is deploying Direct Routing. Their SBC vendor requires that the SBC present a certificate to Teams Phone. The SBC's external FQDN is sbc.contoso.com. The certificate is issued by an internal enterprise CA. During initial testing, the SBC fails to connect to the Teams Phone service. Which configuration change is most likely required?

Add the internal CA root certificate to the Teams Phone trust store using PowerShell.

Replace the internal CA certificate with a certificate from a public CA that includes the SBC FQDN in the Subject Alternative Name.

Disable TLS verification on the SBC to allow the internal CA certificate to be accepted.

Change the SBC external FQDN to match the certificate's common name exactly and re-run the connectivity test.

A company has an SBC that is already configured for Direct Routing. They recently changed the SBC's external FQDN from sbc1.contoso.com to sbc2.contoso.com. What must be updated in the Teams admin center?

The voice routing policy must be updated to reference the new FQDN.

The PSTN gateway's FQDN must be changed to sbc2.contoso.com.

The user's phone number assignment must be updated.

The SBC's TLS certificate must be reissued with the old FQDN.
