"I was honestly skeptical at first — we'd tried two other voice AI vendors and both felt robotic. But after three months with DuetDial, our support team actually stopped dreading the Monday call surge. CSAT went from 72% to 86%."
"The thing that sold me? I interrupted the demo mid-sentence to ask something off-script, and it just... handled it. No awkward pause, no 'I didn't understand that.' My sales team uses it for outbound now and close rates are up."
"We serve customers in the US and Mexico, so they switch languages constantly. Most tools choke on that. DuetDial doesn't. Had one caller go English-Spanish-English in 30 seconds and it kept up perfectly."
"Look, I've integrated a lot of APIs. This one took me maybe 4 hours to get a working prototype. The docs are solid, the WebSocket connection is stable, and when I hit a snag their Discord was actually helpful. Rare combo."
