OnlyDialer (Power Dialer)
Web AppAbout This Project
OnlyDialer is the calling engine of a three-app sales suite I built for insurance and outbound sales teams. It is its own Next.js app and Vercel project at onlydialer.com, deployed separately from the CRM (crm.onlydialer.com) and the SMS platform (sms.onlydialer.com). The three apps share one PostgreSQL database through a Prisma schema in a monorepo package, share the same session and prepaid-billing model, and call each other over authenticated API routes. The dialer runs on the Twilio Voice SDK with local presence dialing, cascade routing, call recording and playback, and 2FA-protected agent logins. When it buys or replaces a phone number it points the voice webhooks at itself and the SMS webhook at the texting app, so inbound texts to a dialer number land in the SMS inbox. It reads the organization's prepaid balance from the CRM's billing API and deep-links into CRM lead records. Each customer organization gets its own Twilio sub-account, Stripe per-seat plus metered billing, plan-based feature gating, and white-label branding on the enterprise tier.
