How It Works

Deploy an AI virtual agent across voice and chat in four steps, from configuration to live handling of real calls.

Configure your agent
Pick a voice, set escalation rules, and connect your knowledge base using a pre-built template.
Test before launch
Run simulated calls and chats to validate accuracy, intent handling, and escalation before going live.
Connect your channels
Link your phone numbers via SIP trunking and add the chat widget, with no change to your current stack.
Deploy and monitor
Go live and track containment, resolution, and sentiment in the analytics dashboard, then refine.
Use Cases

Inbound Customer Support

High call volume and inconsistent answers drive up both cost and handle time. An AI customer support agent answers every inbound call and chat instantly, resolves common questions, and routes the rest to the right person. Service levels hold without adding headcount.

After-Hours Call Coverage

Calls that come in after close go to voicemail, and most callers never ring back. An AI answering service runs the same quality as your daytime team around the clock, booking callbacks or resolving issues on the spot. Your team starts the day with context, not a backlog.

Appointment Booking and Reminders

Scheduling by phone means hold time, phone tag, and double-bookings. The agent checks live availability and can book appointments during the call, send confirmations, and handle reschedules through natural conversation. Pine Park Health raised scheduling NPS by 38% after automating it.

Lead Qualification and Routing

Inbound leads go cold when no one picks up fast enough. The agent answers immediately, asks your lead qualification questions, scores the prospect, and routes hot leads to a rep while logging the rest. Sales spends time on leads that are ready, not on triage.

Outbound Follow-Up Campaigns

Following up after a service interaction matters for retention, but it slips when the queue is full. A batch call campaign reaches every customer automatically, confirms resolution, and flags anything unresolved for review. Follow-up that needed dedicated headcount now runs on its own.

Front-Desk Reception

Need to cover the main line without tying up a front-desk hire all day. Virtual receptionists greet every caller, answer routine questions, and route or take a message around the clock. Nobody waits on hold, and no message gets lost.

Compliance

An AI virtual agent handles sensitive customer data on every interaction.

SOC 2 Type II

Call and chat data runs on SOC 2 Type II certified infrastructure, meeting enterprise security requirements by default.

HIPAA

Healthcare and health-adjacent teams deploy under HIPAA with a self-service BAA portal available in the platform.

GDPR

Caller data is processed under GDPR, covering consent, access rights, and processing records for EU customers.

PII Redaction

Personal identifiers are redacted from transcripts automatically, based on retention rules you configure.

FAQ

Frequently asked questions.

What is an AI virtual agent?

An AI virtual agent is software that handles customer calls and chats through natural conversation, replacing IVR menus and scripted bots. It understands intent, answers questions, completes tasks, and escalates to a human when needed, all on the same AI voice agent platform.

How many calls and chats can an AI virtual agent handle at once?

Accounts start with 20 free concurrent calls and scale to thousands of simultaneous calls and chats with custom concurrency. The platform powers 30+ million calls per month, so a launch or outage spike never puts callers on hold.

What is the difference between an AI virtual agent and a traditional chatbot?

A traditional chatbot follows a fixed decision tree and only handles inputs it was scripted for, which is why it forces people through menus. An AI virtual agent reads intent, handles multi-part requests, keeps context, and completes the task instead of pointing to an answer.

What containment rate can an AI virtual agent reach?

Containment is the share of contacts resolved without a human. Teams handling order status, scheduling, and account questions often contain 60% or more. Medical Data Systems takes every inbound call with a 30% transfer rate, so 70% resolve without an agent.

What types of tasks can an AI virtual agent complete?

Beyond answering FAQs, it completes workflows during the call: checking order status, updating addresses, processing returns, verifying identity, and booking through an AI appointment setter. Data updates in real time, so the task finishes before the call ends.

Is an AI virtual agent secure enough for healthcare and finance?

Yes. The platform is SOC 2 Type II certified, HIPAA-ready with a self-service BAA portal, and GDPR compliant, covering most regulated healthcare and finance work. PII redaction removes personal identifiers, and retention settings control what is stored.

How fast can an AI virtual agent go live?

Most teams go from signup to a live agent in days. Pre-built templates for support, reception, and scheduling get you to a working agent in minutes, and simulation testing validates behavior before any customer hears it. Standard deployments need no engineering team.
