Suggested Answer: A

Communication Manager is working because can make calls out successfully, SBCE is partially working * Notice that the FROM header is an IP address instead of a domain name = avava.com. CM needs to see domain name. IP address to domain conversion is performed by Topology Hiding.

I lean towards option C. If SBCE isn't working, calls won't route.

C doesn’t fit. SBCE is receiving calls, just not routing.

I feel like the public network could be a factor, but I don't recall if that was explicitly mentioned in our materials. Option B might be misleading.

I'm a bit confused about the role of the Avaya Aura Communication Manager here. I thought it was crucial for call routing, but maybe it's not the issue?

This seems similar to a practice question we did where the SBCE was involved. I think option A makes sense since it mentions partial functionality.

I remember studying how the SBCE handles incoming calls, but I'm not entirely sure if it's just a routing issue or something more serious.
