What is an enterprise-focused Session Border Controller (SBC) providing voice and video connectivity from the enterprise IP network to service provider SIP trunks?

Show Suggested Answer Hide Answer
Suggested Answer: B

A Session Border Controller (SBC) is a networking device designed to secure and control voice and video traffic as it enters and leaves an enterprise IP network. An enterprise-focused SBC provides voice and video connectivity from the enterprise IP network to service provider SIP trunks, ensuring that the calls are compliant with service provider requirements. CUBE (Cisco Unified Border Element) is an enterprise-focused SBC from Cisco that provides voice and video connectivity from the enterprise IP network to service provider SIP trunks. CUCM (Cisco Unified Communications Manager), CVP (Customer Voice Portal), and DNIS (Dialed Number Identification Service) are not enterprise-focused SBCs.

I’m not so sure. What about A) CUCM? It’s also related to voice.

C) CVP? Really? That doesn't sound right at all.

Surprised it's not A) CUCM, I always thought that was the main one.

I thought it was A) CUCM, but I guess CUBE makes sense too.

DNIS sounds familiar, but I don't think it's the right answer here. It’s more about number identification, right?

I practiced a question similar to this, and I think CUBE was the right choice for SBCs connecting to SIP trunks.

I feel like CUCM is more about call management, not really focused on SBC functions.

I think the answer might be CUBE, but I'm not entirely sure. I remember it being related to SIP trunking.
