Why not just use Unified Communications Manager for everything?

Wait, are we sure about that? I thought transcoding was needed too.

Gotta enable interworking in Expressway-C for H.323 and SIP!

I’m leaning towards interworking in Expressway-C too, but I also remember something about transcoding in CUCM. It’s tricky to differentiate them sometimes!

I vaguely remember that Expressway-C handles external communications, so maybe interworking should be enabled there? It’s a bit fuzzy in my mind.

I practiced a similar question where we had to choose between transcoding and interworking. I feel like interworking is the right term here, but I can't recall the exact location.

I think this might be about interworking, but I'm not sure if it's in Expressway-C or CUCM. I remember something about SIP and H.323 needing that feature.

I'm not entirely sure about this one. I'll need to review my notes on Cisco Collaboration infrastructure and the differences between interworking and transcoding. Hopefully, I can narrow it down to the correct answer.

Okay, I think I've got this. The key is that they need to communicate with external parties using H.323 and SIP, but internally they want to use only SIP. So the feature they need to enable is interworking, and it should be done in the Expressway-C.

Hmm, I'm a bit confused by the wording here. I'll need to re-read the question and think through the functionality of Expressway-C and Cisco Unified Communications Manager.

This looks like a tricky question about interoperability between different VoIP protocols. I'll need to carefully consider the requirements and think through the different options.

I'd be a bit worried if the answer was D) Interworking in Cisco Unified Communications Manager. That's like trying to herd cats and dogs at the same time, am I right? C) Transcoding in Expressway-C seems like the way to go here.

Haha, I bet the exam writers had a fun time coming up with this one. It's like a game of protocol Tetris, trying to figure out the right pieces to fit together. I'm going with C) Transcoding in Expressway-C, sounds like the most logical choice to me.

Hmm, I'm not sure about this one. I think B) Transcoding in Cisco Unified Communications Manager might be the answer, as CUCM is the main call control and could handle the transcoding between the different protocols.

I think the correct answer is C) Transcoding in Expressway-C. The requirement is to communicate with external parties using H.323 and SIP, and the internal endpoints should only be registered on SIP. Expressway-C is the right component to enable interworking and transcoding for this scenario.
