Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent system update. Has there been any significant changes to our UCaaS infrastructure in the last month?

Why it matters: Recent changes often correlate with sudden spikes in issues. Expected answer: Yes, there was a system update two weeks ago. Impact on approach: If confirmed, we'd focus on rollback options and code review.

• Considering the nature of audio quality issues, I'm curious about our network performance. Have we seen any changes in network metrics like latency or packet loss?

Why it matters: Audio quality is heavily dependent on network performance. Expected answer: There's been a slight increase in average latency. Impact on approach: We'd prioritize network optimization and potentially engage with our ISP partners.

• Given the broad term "audio quality," I'm wondering about the specific nature of the complaints. Are users reporting echoes, drops, or garbled speech?

Why it matters: Different types of audio issues point to different root causes. Expected answer: Most complaints mention garbled speech and occasional drops. Impact on approach: This would lead us to focus on codec issues or network stability.

• Thinking about our user base, I'm curious if this is affecting all customers equally. Are the complaints concentrated in specific geographic regions or among particular types of users?

Why it matters: Localized issues suggest different solutions than global problems. Expected answer: The issues seem more prevalent in the West Coast region. Impact on approach: We'd investigate regional network infrastructure and potentially local ISP performance.
