VoiceInfra

What it is

VoiceInfra is a no-code builder for AI voice agents that answer and place phone calls, aimed at operations, support and contact-center teams that already run a phone system. The company's own words are "VoiceInfra is designed for non-technical users. The point-and-click interface requires zero coding." The same agents can also be embedded on a website as a voice and chat widget, so the product sits in 2 directories at once: voice agent builders and chatbot builders. The site says it runs in 4 deployment regions, US, EU, ANZ and PK, with local phone numbers, carrier interconnects and in-region storage, and its footer lists country pages for the United States, United Kingdom, Spain, UAE, Saudi Arabia, Australia and India.

What you build and how

You build an agent in the AI Agent Builder. There are 2 ways in: a guided 2-step wizard for simple agents, and a visual drag-and-drop canvas for workflow-based agents with smart routing and multi-step conversations. The site says no code is required. You pick from industry-specific templates, set the voice and the knowledge base, test in a sandbox, and deploy to your phone system with a single click. The use-case list names real estate, healthcare, financial services, retail, hospitality, education, automotive, recruitment, government and utilities.

The data layer is a knowledge base rather than a database. Agents are described as running on RAG-powered knowledge bases that turn your documents and website into working knowledge, and the FAQ says there is "zero training time required." The knowledge base takes PDFs, DOCX and TXT uploads or a crawl of your site, with review before ingest. For actions, the site points to Model Context Protocol, which lets an agent book appointments, update a CRM and send notifications in real time during the call. An MCP Tool Integration card names Microsoft Teams, Asana and Salesforce, and lets you pin the exact tools each agent may call. The integrations menu names Calendly for voice appointment booking and Zoho for customer records.

Telephony is the center of the product. VoiceInfra connects to any telephony system through SIP, and the site names 3CX, Yeastar, FreePBX, Avaya, Cisco, Mitel and Asterisk. Agents register as extensions on your existing PBX, next to your human staff. The navigation promises a "60-Second SIP Setup", while the closing call to action says "5 minutes, zero downtime". You can import numbers from Twilio, Telnyx or any SIP provider in one click, or buy local, national and toll-free numbers from VoiceInfra across multiple countries. The features menu also lists batch outbound calling, described as scaling outbound without scaling headcount, and shows "500+ AI calls daily in 5 languages" as an outbound example.

Voice quality comes from premium voices from ElevenLabs, Cartesia and Rime AI, with sub-second response times according to the site. It states support for 30+ languages with native-quality voices, and says the system detects the caller's language preference and routes to a matching voice model: American English for US customers, Castilian Spanish for Spain, Oxford accents for UK callers. The features menu adds Multi-LLM Support across 5+ providers and claims smart routing can "Slash AI costs by 70%," a company claim.

When an agent cannot answer, the site describes a smart escalation with a full context handoff: the human agent receives the conversation history and customer background, so the caller does not repeat the issue. The agents are also said to handle multiple calls at once and to run around the clock.

For the chatbot side, the same agent handles phone, WhatsApp and web from one place: WhatsApp Calling and Messaging covers voice calls and text conversations over WhatsApp Business. The Web Embed option puts voice and chat directly on your site. Visitors start a conversation instead of filling out a form, the agent captures the lead, answers questions and routes to the right team member. For developers, the API section promises "full programmatic control" for integrating agents into workflows, a CRM, a helpdesk or your own application. The site claims connections to 100+ CRMs, phone systems and business tools, while the integrations link in the menu says "Explore 40+ integrations", so the 2 counts differ.

The regions section describes in-country deployment. For Pakistan it describes local SIP peering with PTCL and Pakistani carriers, and recordings, customer data and connectivity kept in-country. It adds "Deploying in more regions soon" and invites you to talk to the infrastructure team about a specific region.

What the pages say about plans, results and support

The pricing section is headed "Simple, transparent pricing" and says every plan includes the full platform, all AI providers, PBX integration and infrastructure, with scale as the difference. Launch, for after-hours and solo operators, is $49 a month with 175 minutes included, 1 agent, 2 concurrent calls, 1 voice clone, 3 knowledge bases and email support with a 48h response. Starter, marked Most Popular, is $99 a month with 350 minutes, 3 agents, 5 concurrent calls, 1 voice clone, 7 knowledge bases and a 36h email response. Professional is $249 a month with 900 minutes, 5 agents, 10 concurrent calls, 3 voice clones, 15 knowledge bases and priority support within 24h. Professional Plus is $399 a month with 1,500 minutes, 7 agents, 15 concurrent calls, 5 voice clones, 25 knowledge bases and an 18h priority response. Every tier includes a PBX extension. "All plans billed monthly. Additional minutes and concurrency available." Enterprise covers custom integrations, deployment support, voice design and compliance work through Enterprise Sales. The FAQ adds a free trial with a demo number you can set up in minutes.

The savings claims are the company's. The site says businesses "typically reduce customer support costs by 40-65%" and that one AI agent can replace 3-5 human agents. It describes one logistics client that automated 34% of its calls, and contrasts the setup time with training human agents, which it puts at 6+ weeks. It also says customers often have full 10-minute conversations thinking they are speaking with humans. Read these as vendor claims, not benchmarks.

Support is described as 24/7 technical support, guided onboarding and documentation, with integration help, voice customization guidance and optimization resources, and the site lists direct engineering support. Its feature table marks on-premise deployment and MCP integration for the Enterprise tier. The pages name no compliance certification.

Who it suits and who it does not

VoiceInfra suits a support or operations team that already runs a business phone system and wants AI agents sitting on it as extensions, without a development project. Contact centers, healthcare practices scheduling patients, insurers, logistics dispatchers and home-service companies are the industries the site spotlights. Telecom operators and managed service providers get their own page ("AI for Telecom MSPs"), so it serves resellers with PBX customers as well as end businesses.

A solo operator can start on the $49 Launch plan, but the strongest features assume a SIP-capable phone setup, and a founder who only wants a weekend voice bot will pay for PBX plumbing they do not use. A developer who wants to write agent logic by hand will lean on the API and may find the canvas limiting. And since the headline savings figures come from the company's marketing, a team that needs hard numbers should pilot with its own call data first.
