FAQ
Questions, answered
What counts as a "lost" or "cold" lead it can work?
Any lead sitting in your CRM that hasn't converted — unanswered follow-ups, stalled deals, or leads that went cold after the first call. Converse re-engages them by voice and email automatically.
Does it actually close deals, or just re-engage?
Both — it closes what it reasonably can on its own and hands off the rest to a human rep with full call and email context, not a cold restart.
Which telephony providers does it support?
Plivo, Exotel, and Twilio natively, plus any SIP-compatible carrier through FreeSWITCH for full infrastructure control.
How many calls can it run at once?
No hard concurrency limit — it scales from a single call to thousands running simultaneously without added infrastructure work.
Where does call and lead data live?
On your own cloud or fully on-prem — call data never leaves your network, by deployment design, not just policy.
How is NN Converse priced?
Pricing scales with call volume. Pilots start with a small fixed fee; enterprise and sovereign deployments are custom-quoted after a strategy call.
