How we sorted: products with a firm real-bill estimate at 300 calls a month first (cheapest first), then agents by their lowest listed monthly plan, then products without a comparable monthly figure. Prices are copied from each vendor's public pricing page on the date shown; plan names and billing notes (per seat, billed yearly) are kept as the vendor writes them. "not published" or "Contact sales" means the vendor doesn't publish a price; we don't guess. Real bill = our estimate from public pricing: 300 calls/month, average 3 minutes per call (900 talk minutes), billed monthly (not annual), US local number, no add-ons. Prices change; confirm with the vendor.
