AI Call Agent by Semicolon · New Service
Human-quality AI voice agents that handle inbound and outbound calls — sales, support, scheduling, and more. 24/7. No hold times. Sounds just like a person.
Never miss a call. The agent instantly picks up, handles FAQs, resolves issues, and escalates to a human when needed.
Automate sales outreach, appointment reminders, follow-ups, and lead qualification at scale — without hiring a team.
24/7 availability — across time zones, languages, and call volumes. Zero wait time. Zero burnout.
What It Can Do
Every capability you'd expect from a world-class call centre — delivered by an AI agent that never sleeps, never has a bad day, and scales instantly.
Upload FAQs, scripts, product info, and SOPs. The agent learns your tone, processes, and knowledge base — and answers accurately from day one.
Ultra-low latency, natural speech with no robotic pauses or synthetic AI sound. Callers won't know it's not a person — unless you want them to.
Support customers in 30+ languages with native-sounding, expressive speech. Choose from multiple voice profiles to match your brand identity.
No months of setup. We configure, train, test, and deploy your AI call agent in as little as 48 hours — fully integrated with your workflows.
Connects with your CRM (HubSpot, Salesforce), helpdesk (Zendesk), calendar (Cal.com), and phone systems. Plug-and-play with your existing tools.
No contracts. No setup fees. No monthly minimums. Transparent, usage-based pricing — you only pay for the calls that happen.
The agent detects when a customer needs a human, and hands off the call seamlessly — with full context already transferred.
Every call is logged, transcribed, and summarised. Track resolution rates, sentiment, and trends — and continuously improve performance.
Data encrypted in transit and at rest. Compliance-ready infrastructure. Your customer data stays private and is only used for your agent's performance.
Use Cases
From small businesses to enterprise teams — our AI call agents are deployed across sectors where conversations matter.
Outbound prospecting at scale. Inbound lead capture and qualification. Books meetings directly to your calendar. No human call agent required.
Handle common queries, reduce ticket volume, and resolve issues at first contact — 24/7, without growing your support headcount.
Book, reschedule, remind, and confirm appointments automatically. Works for clinics, law firms, real estate, financial services, and more.
Status updates, returns, account changes, and billing inquiries — all handled without human involvement, at any hour.
Patient intake, triage, appointment booking, and after-hours support. Reduce administrative burden while improving patient access and experience.
Never miss a lead or client call. Qualify prospects, capture intake details, and route calls to the right team — professionally and instantly.
The Process
A structured, fast path from onboarding to live calls — with our team guiding you every step.
Share your business data — FAQs, call scripts, product information, tone guidelines, and any existing integrations. We handle the rest.
Our team configures and trains a voice model specifically for your business — personality, tone, language, escalation paths, and integrations.
We run the agent through real-world call scenarios, stress-test the knowledge base, and QA the voice experience before anything goes live.
Deploy to your phone system. Start taking and making calls. Add more lines, languages, or use cases on demand as your business grows.
Pricing
Transparent, usage-based pricing with no setup fees, no monthly minimums, and no long-term contracts. You're billed only for the calls that happen — nothing more.
FAQ
Not at all. Our team handles all the technical configuration, training, and integration. You simply share your business information and we take it from there. No code. No complex setup.
Yes. Our AI agents are built on large language models that maintain full context across a conversation. They understand intent, handle ambiguity, remember what was said earlier in the call, and respond naturally — not just matching keywords to scripts.
Our agents support 30+ languages with native-sounding, expressive speech. We can deploy multilingual agents that switch between languages mid-conversation when needed. Specific language availability can be confirmed during your onboarding call.
We integrate with major telephony providers and SIP-compatible phone systems, as well as leading CRMs like HubSpot and Salesforce, helpdesks like Zendesk, and scheduling tools like Cal.com. Most integrations are completed during setup at no extra complexity to you.
The agent detects escalation signals — either an explicit request or detected frustration — and seamlessly transfers the call to a human agent, along with a full summary of the conversation so the human doesn't have to ask the customer to repeat themselves.
Absolutely. All data is encrypted in transit and at rest. Your business data is only used to train your specific agent and is never shared with other clients. We operate on enterprise-grade infrastructure with strict data governance standards.
Our agents are built on state-of-the-art voice synthesis with sub-second response latency. The result is natural, expressive, and human-quality speech with no robotic pauses or synthetic monotone. Most callers cannot distinguish the agent from a human representative. We can also configure the agent to proactively disclose it's AI — depending on your preference and regional compliance requirements.
