What it does in the flow
Retell powers step 3, prequalify (and drives step 2's dialing and step 4's transfer mechanics too). Connect your own Retell account with one API key — we validate it live against Retell's API and auto-discover every agent on the account into a dropdown, so there's no manual agent-ID copy-pasting. Your campaign picks an agent, and calls, transcripts, dispositions, and transfer events stream back through Retell's webhooks in real time.
Retell exposes capability flags that drive what the connect UI (and your campaign options) unlock:
Because Retell supports dynamic transfer numbers and a whisper message, it's the provider we point tenants toward when the campaign's whole point is a live warm transfer to a buyer — which, per the canonical flow, is most campaigns on this platform.
Current status: live
Connect a Retell account in the dashboard today. The full path is proven on real outbound calls: we validate your key live, auto-discover your agents, dial on your schedule with the calling-window and retry rules enforced, run your qualification script on every connect, and stream transcripts and dispositions back in real time. The warm-transfer step — a dynamic transfer number and a whisper before the bridge — is built and available. As with any new calling setup, run a couple of test transfers to your own numbers before a first live campaign so you can hear the whisper and confirm the bridge on your own gear.
FAQ
What do I need to connect Retell?
Just your Retell API key. We validate it live the moment you paste it in, and every agent on your account shows up in a dropdown automatically — no manual configuration.
Do I need Retell specifically, or does ElevenLabs work too?
Either is fine at the platform level — connecting one provider is enough to run campaigns. The constraint is per-campaign: an agent belongs to a provider, so that provider must be connected before that campaign can go live. Retell is our current recommendation for warm-transfer-heavy campaigns because of its whisper/dynamic-transfer support.
