AI in Voice API, working on its own.
AI that takes the action, not just the note. Running inside the network, on your brand.
AI IVR replacement
Swap keypad menus for an AI agent that understands the caller and routes or resolves directly.
Smart call routing
AI reads the caller’s intent and history, then sends the call to the best queue or agent.
Missed call follow-up
When a call goes unanswered, AI sends a callback offer or message and books the return call.
