What does the Pro tier add over Starter?

At $299/month, Pro includes everything in Starter and adds the 24/7 AI voice: it answers, converses, qualifies and books over the phone, introduces itself as your business's assistant, and warm-transfers urgencies to you with context. It also adds WhatsApp confirmation to the end customer and the urgency threshold with live-call transfer. When several lines or locations come into play, the multi-line tier starts at $499/month.
