You have a Microsoft Teams Phone deployment that uses Direct Routing. The deployment has the following configurations:
- Direct Routing Session Border Controller (SBC) public IP subnet: 198.51.100.0/24
- Teams client external IP subnet: 203.0.113.0/24
- Teams client internal IP subnet: 192.168.0.0/24
You need to configure the network topology to support emergency call routing.
Which network range should you add to the trusted IP addresses?
A. 52.112.0.0/14
B. 198.51.100.0/24
C. 203.0.113.0/24
D. 192.168.0.0/24
