Common questions
Is Sysevo cheaper than Retell?
Retell's published range is $0.07–$0.31/min depending on the model and features you turn on, against Sysevo's flat $0.10–0.14/min PAYG rate. Retell's number is for the call itself — the CRM, memory, analysis and follow-up automation are yours to build or buy separately. Sysevo's rate already includes all of that, so the two numbers aren't really pricing the same thing.
Does Retell include a built-in CRM?
No — Retell is a voice agent platform, not a CRM. You integrate your own. Sysevo ships with a full CRM and caller memory natively, so contacts, pipeline and call history already live in the same system as the agent.
Does Retell offer white-label like Sysevo?
Retell has a tiered partner program. Sysevo's white-label puts your own brand on your own domain as a full reseller model, not a bolt-on partner tier — your clients never see Sysevo.
