Collaboration Communications Systems Engineer — Question 163

You have a Teams Phone deployment.

You have a site named Site1 that contains a Session Border Controller (SBC) named SBC2. SBC2 uses Direct Routing and does NOT have local internet connectivity.

Site1 has an MPLS connection to a datacenter that hosts another SBC named SBC1. SBC1 uses Direct Routing.

You need to provide Enterprise Voice to the users in Site1 by configuring SBC2 to use SBC1.

What should you configure?

Answer options

Correct answer: B

Explanation

The correct answer is B, 'proxy SBC', because it allows SBC2 to route calls through SBC1, which has internet access, thus facilitating Enterprise Voice services. The other options, while relevant to routing and call management in different contexts, do not specifically address the need to configure SBC2 to rely on SBC1 for internet connectivity.
