Hi team, I'm curious to know how you're working with production audio. We're finding a noticeable portion of callers with degraded audio (likely due to older phone models, the intermediary phone provider before Twilio etc). We've considered: - Getting customers to port their number to a 'good' telco - Switching from Twilio to Telnyx or other provider - Pre-process audio between Twilio/VAPI Open to any thoughts or suggestions!
