AI audio call automation is a software system that handles inbound and outbound telephone calls using AI-powered voice synthesis, natural language processing and large language model reasoning, without requiring human staff on each call. For a London business, the system connects to a Twilio phone number, listens to callers using speech-to-text transcription, processes the caller's intent through OpenAI or Claude, generates a spoken response using ElevenLabs voice synthesis and takes actions such as routing the call, booking an appointment or updating a CRM record. Inbound automation handles call routing, qualification, appointment booking and message capture. Outbound automation dials lists of contacts for campaigns, reminders, renewal prompts and follow-up sequences. Softomate builds AI audio call automation using Twilio, ElevenLabs, OpenAI, GoHighLevel and Zapier for London businesses, with projects starting at 2,000 for focused outbound automation and 4,000 to 12,000 for full inbound and outbound call platform builds.
