## Description

Stop jumping between tabs to manage your voice AI infrastructure. If you're running a fleet of agents, you know the pain of hunting through dashboards to find a specific call transcript or tweaking an LLM prompt one by one. This Connector changes that by letting you treat your voice operations like a conversation. You can ask your agent to spin up a new persona, check the status of a phone number, or pull a transcript from a call that happened ten minutes ago. It puts your entire voice stack inside your chat interface. You can find this in the Vinkius catalog alongside other heavy-hitting industry tools. Instead of manually copy-pasting data or navigating complex menus, you just give instructions. Your AI client handles the heavy lifting of interacting with the Retell AI API. It's about moving from manual management to direct action. You get to focus on the conversation logic while your agent handles the plumbing of the telephony world.
