When phone volume spikes, the failure mode is predictable: long holds, rushed agents, and customers repeating themselves.
The teams that fix it fastest don’t just “add a bot.” They connect telephony, routing, CRM, and analytics so the experience feels coherent end to end in an AI contact center.
Buyers comparing top companies integrating AI voice agents with contact centers usually want two things at once: reliable plumbing and a voice interface that doesn’t sound wooden. The best companies integrating AI voice agents with contact centers tend to prove they can deploy safely inside real operations, then iterate without dragging you into a locked contract. That mix is also what separates pilots from production grade voice AI.
Best Companies Powering AI Voice Agents in Contact Center Infrastructure
Impekable approaches call automation like a product build, not a one-off integration. Based in Silicon Valley, the studio designs conversational voice agents and wires them into platforms like Twilio, pairing natural speech with practical IVR logic. For many enterprises, the pitch is simple: 24/7 coverage that reduces repetitive inquiries while keeping the experience personal.
Their delivery style emphasizes design up front, then clean integration into existing service workflows — which helps teams avoid “two support systems” running in parallel. Impekable also carries broader UI/UX and engineering depth, so the same team can connect the voice layer to web, mobile, and internal tools. That blend makes them one of the best AI voice agent development companies when the goal is a single experience across channels.

If you’re building around Salesforce as the system of record, their playbook is designed for that reality.
What stands out is the operational focus: dynamic IVR, intent-driven routing, transcription, and agent assist that fits the supervisor’s world, not just the demo. A published case example points to strong self-service impact, which is often what teams mean when they ask for best AI voice agents for contact centers. Their work sits comfortably in a modern contact center AI stack where CRM and telephony must behave like one system.

For teams already committed to AWS, the architecture choices tend to feel familiar and supportable.
The company also offers ConnectPath CX, which extends Amazon Connect with features around self-service, AI capabilities, and workforce optimization. That’s useful when internal teams don’t want to stitch together five add-ons to get basic visibility. In practice, CloudHesive sits among top AI voice agent developers for contact centers when the backbone is Amazon Connect and the roadmap includes ongoing managed operations.

Miratech brings long-running enterprise IT services into contact center transformation, with a strong focus on Google Contact Center AI and CCaaS/UCaaS integrations. Their work typically spans voice and chat bots, agent assistance, predictive routing, and the integrations required to make those features dependable. If a contact center program touches multiple vendors, this kind of systems integration background matters.
Case examples describe voice assistants built with Dialogflow CX and Speech-to-Text, including integrations with Genesys to automate enrollment and scheduling flows. That’s the kind of practical automation that improves containment without breaking regulated workflows. For organizations that treat AI for call center as a multi-year operating model, Miratech can act as the integrator that keeps the pieces aligned.

Thunder is a Salesforce implementation partner that has leaned into voice automation through Agentforce Voice. Their focus is practical: voice agents that handle routine calls like order status, returns, and account updates, while integrating directly with Service Cloud Voice. For teams who already live in Salesforce, this can reduce the “integration tax” that often slows down rollout.
Thunder also markets a QuickStart approach that targets going live in about eight weeks, which can be appealing when leadership wants results on a calendar, not a roadmap. The service catalog includes generative IVR and callback automation designed to reduce pressure on live agents. When buyers talk about AI voice agents customer support, this is the kind of scoped, repeatable deployment that often lands.
Tykans Group is a Calgary-based technology company with deep experience implementing and supporting contact center systems. They also build broader communication solutions like mass notification, appointment reminders, and billing automation, which often sit adjacent to call center operations in public-facing organizations. Their project history suggests a delivery culture built around deadlines and high-stakes information.
For contact center work, they emphasize platform implementation and support, plus conversational AI and chatbot integration where it fits. That makes Tykans a practical choice when the job is less about a flashy demo and more about keeping service stable during change. For organizations evaluating top companies integrating AI voice agents with contact centers in healthcare or community service contexts, that operational bias can be valuable.

The solution is positioned for omnichannel environments using Service Cloud Voice plus integrations with AWS and Genesys. Instead of replacing agents, the design supports them with recommendations and sentiment signals, which can help reduce escalations. For companies that want AI call center improvements without rewriting their stack, EPAM can bring both engineering depth and platform experience.

They also highlight AI-focused capabilities like speech and text analytics, voice biometrics, and agent coaching, aligning the build with measurable contact center outcomes.

For teams weighing contact center outsourcing AI, a boutique partner with managed service options can reduce ongoing burden.

Choosing A Partner That Works In Production
The easiest mistake is picking a voice demo that can’t survive your queues, QA rules, and escalation paths. Start by asking how the vendor handles call flows, intent routing, and handoffs to humans — then validate how they log outcomes inside your CRM. The best companies integrating AI voice agents with contact centers tend to show strong integration discipline and clear iteration cycles once real calls start hitting the system.
Think about where your operational burden will live after launch: monitoring, retraining, compliance checks, and reporting. If your environment is Salesforce-first, a specialist online reputation management agency style approach won’t help; you need a team that can run a true contact center AI program and keep it stable as you expand. Choose with that reality in mind, and AI voice agents customer support becomes a durable capability instead of a short pilot.
