Comparison
Retell's $0.07/min base is just the starting line.
What a minute of voice AI actually costs when you're running a call center — not a hackathon project. Base rates, add-ons, and the line items that don't make the landing page.
Retell's base rate covers their voice engine. LLM inference, knowledge base lookups, batch calling, and branded caller ID are all separate charges. Here's what a real production minute looks like:

Start Free PilotSIP-native architecture
Direct SIP trunk integration with VICIdial, Trackdrive, Five9, Genesys. No WebSocket middleware layer between your dialer and the AI.
Built-in AMD
Async voicemail detection hangs up on machines in ~4 seconds. You stop paying for minutes spent talking to answering machines.
Warm and cold transfer
AI qualifies the lead, then transfers live to your closers via SIP REFER or Twilio redirect. No custom code required.
Dual-channel recording
Separate AI and caller audio tracks. Automatic compliance disclaimer. Ready for QA review and regulatory audits.
Dialer integration out of the box
VICIdial and Trackdrive already running in production with paying clients. Plug in your dialer, not a GitHub repo.
WebSocket-based API
Designed as a developer platform. You connect via WebSocket and build the call flow logic around their voice engine.
No built-in AMD
Voicemail detection is not part of the platform. You either build it yourself or absorb the wasted minutes.
Transfer requires custom logic
Call transfers aren't native. You handle routing, handoff, and hold logic through their API and your own backend.
Recording is separate
Call recording exists but compliance disclaimers, dual-channel splitting, and storage are your responsibility to configure.
You build the integration layer
Connecting to VICIdial, Trackdrive, or any production dialer means building and maintaining the glue code yourself.

The $0.07 covers Retell's voice engine only. LLM inference is billed separately based on which model you choose ($0.006 for Llama up to $0.06 for GPT-4o). Then add knowledge base access, batch calling fees, branded caller ID charges, and telephony. For a production outbound campaign, these add-ons stack up fast.
Retell's enterprise rate of $0.05/min replaces the $0.07 base only. LLM costs, knowledge base, batch calling, branded caller ID, and telephony are still billed separately on top. The real enterprise total typically lands between $0.10-0.20/min depending on your stack. Klariqo's $0.10-0.15/min includes everything.
Yes. We accept inbound SIP transfers and originate outbound via SIP or Twilio. VICIdial and Trackdrive are already live in production with paying clients. If your dialer supports SIP, we can connect.
Currently live with SSDI, Final Expense, ACA health subsidy, and general insurance qualification. Expanding into debt relief, tax, mortgage, and mass tort. Each vertical gets its own qualification script and compliance guardrails.
We offer 300-minute pilot programs for enterprise clients. You test with real calls, real transfers, and real data. If the unit economics don't beat what you're paying now, you walk away.
