Frequently asked
- What is the difference between a conversational AI platform and a contact center platform?
- A conversational AI platform builds and runs automated voice or chat agents. A contact center platform routes conversations to human agents with queues, skills-based routing, and supervisor tooling. Full-stack platforms do both, so an AI agent can handle a call and hand off to a human on the same system when it needs to.
- Does Orbit publish its voice-agent latency?
- Yes. Orbit publishes its voice-agent latency budget broken down by stage — endpointing, transcription, model response, and speech synthesis — with the full methodology behind every figure, so the target it's engineered against is something you can check rather than take on trust. Measured production percentiles publish on the same page once they're live.
- Can one platform run both AI voice agents and human agents?
- On Orbit, yes. AI voice agents run on the same account as the contact center, so a call can start with an AI agent and hand off to a human in a skills-based queue, with callback-in-queue and supervisor wallboards, without moving between systems.
