Option C is the culprit here, G.711 is needed for proper DTMF.

Not sure if it's just DTMF not being negotiated, could be something else too.

Surprised that G.729 could cause this issue, I thought it was just a codec choice!

I think it's more about the payload type being wrong, like option A.

Definitely sounds like DTMF wasn't negotiated on the call.

Okay, let me think this through. The options mention consumers, CxOs, lead architects, and sponsors - those all sound like they could be relevant stakeholders in a system. I'll need to review the TOGAF definitions to pick the best answer.

Hmm, I'm a bit unsure about this one. I know planned orders are important, but I'm not sure which of these options is the best description of their purpose.

My memory is a bit fuzzy—wasn't there something about needing to authenticate before using that method? That might affect the answer too.

I'm a little confused on the difference between entity recognition and key phrase extraction. Can someone clarify which one is better for identifying the main talking points?
