Voice Agent

Overview

Voice Agent is an AI-powered calling platform built for service businesses that need to manage customer communication without relying on staff for every routine call. It handles inbound inquiries and outbound campaigns through natural voice conversations, then connects customer requests to actions such as booking appointments and scheduling callbacks. Businesses manage agents and contacts in a central dashboard, with call history and campaign activity kept together for a clear record of each interaction.

Challenges

Service businesses can receive more calls than their teams can answer. Customers may wait during busy hours or call outside working hours, leaving inquiries and appointments at risk of being missed.

Outbound reminders, lead follow-ups, and callbacks take staff away from conversations that need human attention. Repeating these tasks manually also makes consistent outreach difficult.

Traditional calling systems often leave conversations disconnected from calendars and customer records. Staff then have to update multiple tools by hand, which can lead to missed follow-ups and incomplete records.

The platform needed an AI agent that could understand customer intent, respond naturally, and complete useful business tasks during the conversation rather than only read scripted replies.

Solution highlights

We built a conversational AI platform that connects voice communication with appointment scheduling and customer management. For inbound calls, the agent listens to requests, responds in context, checks available slots, and helps customers book or reschedule appointments.

Businesses can configure outbound campaigns for appointment confirmations, reminders, lead qualification, and customer follow-ups. Calling windows and retry rules give teams control over when automated outreach happens.

Inbound and outbound workflows share the same operational record. An unresolved inquiry can create a follow-up task, while an outbound conversation can lead directly to a booking or callback.

A central dashboard brings agent settings, contacts, call history, campaign activity, and outcomes into one workspace so teams can manage daily calling operations without switching between separate systems.

Our Role & Approach

WanderCode designed and developed the Voice Agent platform across its backend architecture, AI calling workflows, and management dashboard. We focused on conversational context and real-time voice processing so agents could recognize intent and respond to the situation. Backend services manage calls and campaign schedules, while background workers handle automated tasks. Connected workflows turn conversations into appointments and follow-up actions. We also built the tools businesses use to configure agents and review customer interactions.

Technology Stack

Backend: Python, FastAPI, PostgreSQL. AI and voice: OpenAI Realtime API for conversational intelligence and speech interaction. Task processing: Celery and Redis for background jobs and campaigns. Real-time communication: WebSockets for live voice sessions. Integrations: telephony services, calendar APIs, and webhooks. Infrastructure: Docker for containerized services and development environments.

Outcomes

Voice Agent brings customer calling and appointment management into one connected platform. AI agents can answer routine inquiries outside regular working hours and help customers arrange appointments without requiring staff to be available around the clock.

Automated reminders and scheduled follow-ups help teams stay in touch with customers while reducing repetitive calling work. Staff can focus on conversations that need their judgment.

The dashboard gives businesses a clearer view of conversations, appointments, and customers who need further attention. The platform supports growing call volumes while keeping communication more consistent.
