Three ways UCaaS, CPaaS and voice platforms can add AI agents without rebuilding their stack

Business customers are asking their communications provider the same question: what can you do with AI? For UCaaS, CPaaS and voice platform providers, that is both an opportunity and a problem.

Building it in-house means speech recognition, voice synthesis, language model orchestration, guardrails, monitoring and, above all, the industry knowledge and integrations that make an AI agent useful to a dental practice, a hospital or a bank. That is a lot of product to build before the first customer pays for it.

There is another way: plug a production-ready AI platform into the voice infrastructure you already run, and sell it as your own. Here are the three ways we see platforms doing that. They can be used on their own or combined.

1. Network-native: AI on the numbers and trunks you already serve

The first option connects AI directly to the voice network, so calls reach it without any change to how your customers use their phones. There are four ways in, and none of them needs changes to the core to start:

• Call controller: a routing rule sends AI-enabled business numbers to the AI platform over a SIP trunk. No HSS, S-CSCF or SBC change.
• Enterprise SIP trunk: AI per trunk or channel, steered by the call controller, while the customer's PBX stays exactly as it is.
• IMS core: an initial filter criterion (iFC) brings AI to any mobile or fixed IMS subscriber, and fails open if the AI is unavailable.
• SBC listen-only: the SBC forks a copy of the audio (SIPREC) for transcription and analytics, so the AI is never in the call path.

In every case only the selected numbers, trunks or subscribers reach the AI, network headers are preserved, calls continue on the normal path if the AI can't be reached, and emergency calls are never routed to AI.

2. On your voice AI stack: your agent answers, ours takes it from there

Some platforms already have their own voice agent. In that case it can stay the front door: it greets the caller, identifies them and works out what they need.

When the request needs industry depth, such as booking a dental appointment in the practice management system or handling a card dispute within a bank's policies, the call is handed over by SIP to an industry agent, with the caller's identity, intent, transcript so far and customer ID. Nobody has to repeat themselves. The outcome and a summary go back to your agent, or the call goes to a person with full context.

Because the industry agent can run on your speech-to-text, text-to-speech and language models, the caller hears one consistent voice throughout. You keep the front door and the customer relationship; the AI platform adds the industry language, integrations and guardrails.

3. Fully OEM-integrated: your engine sells and provisions it

The third option is about how the service is sold, provisioned and billed rather than how calls reach it. Here the AI platform stays invisible:

• Provisioning API: your ordering engine creates the customer tenant, deploys an agent from an industry template and sets or changes its tier.
• White-label: your brand on the customer portal and agent studio, with single sign-on to your identity platform.
• Usage and billing: usage records per tenant, number, agent, minute or subscriber, feeding your own rating and billing.
• Multi-tenant lifecycle: thousands of customers isolated by tenant, with upgrade, suspend and cease driven by your systems.

What you can sell

Once AI is connected, the same platform supports a range of services that fit the lines and seats you already sell:

• AI front desk: an AI receptionist, missed-call and after-hours handling and speech-driven routing for small businesses and branch offices.
• AI contact centre: AI agents alongside human agents, live agent assist and AI summaries written straight into the CRM.
• Compliance and insight: recording, transcription, audit trails and speech analytics for regulated businesses.
• AI outbound: reminders, follow-ups and campaigns for healthcare, utilities and collections, within your caller-ID policy.
• Call protection: AI call screening, an AI assistant in place of voicemail and live captions for consumers and sole traders.

Each industry starts from a template, with its knowledge, integrations, policies and escalation rules already defined: dental practices and clinics, hospitals, banks, hospitality, retail, professional services and more. The agents connect to the systems your customers use, from CRMs such as Salesforce, HubSpot and Dynamics to practice management, EHR, ERP, billing and ticketing systems.

Low risk, one step at a time

Most platforms start small: listen-only analytics on their own customer service calls, then a pilot on a few business numbers and trunks, then packaged services for business customers, and finally services for every subscriber. At each step the integration is network configuration rather than a development project.

Commercially, the model can follow how you already sell: wholesale usage pricing, revenue share, a platform licence or referral and co-sell.
