AI context is the new lock-in, and no vendor in this roundup says how you get it out
UC Today publisher Rob Scott published a roundup on 28 October 2026 arguing that the real contest in UC and contact centre AI is over who holds an organisation's accumulated context. Zoom acquired Onyx, an open-source enterprise search platform founded in 2023 with a community of more than 30,000 developers. Zoom says Onyx will stay open source, model-agnostic and self-hostable. Microsoft put Contact Center Intelligence into public preview. It has connectors for Five9, Cisco Webex Contact Center and Avaya, and it bills through Copilot Credits. Microsoft also opened a Voluntary Exit Offer to around 60,000 eligible employees, roughly a quarter of its workforce. RingCentral reported Q3 2026 revenue up 5.9% to $676 million, subscriptions revenue up 6% to $653 million, a 24.7% non-GAAP operating margin and gross debt of about $1 billion. The copy we read cuts off partway through the RingCentral section. Five9 and Logitech are named in the standfirst, but we saw nothing on them.
What is "AI context", and why are vendors fighting over it?
AI context is the accumulated record of customer conversations and internal knowledge, spanning calls, chat, tickets, wikis and CRM records, that an AI agent retrieves to answer well.
Zoom's pitch is that generic models lack "the relevant perspective" on your customers and processes. Its Unified Context Layer captures meetings, calls and chat. Onyx adds the wikis, tickets and CRM data that sit outside those channels. For a support team, that is the material your AI agent draws on when it answers a customer, so whoever indexes it shapes how good the agent is.
Does Microsoft's contact centre move threaten my current CCaaS vendor?
Potentially. Microsoft's preview puts its AI agents on top of Five9, Webex or Avaya, so the platform stays put while the AI layer, and what it learns, may end up with Microsoft.
The coverage doesn't say where the context is stored or who can reuse it, and that is the question to press. The product is also only in public preview. Scott notes the odd juxtaposition of Microsoft trimming its own payroll while selling AI into other companies' service operations. His practical tip is to ask your Microsoft account team who your owner will be in January. Consumption billing through Copilot Credits also makes cost per conversation something you need to model yourself before a pilot grows.
How much should I trust the AI revenue figures vendors are quoting?
Cautiously. RingCentral's near-15% figure is ARR from customers on a native paid AI product, so it appears to measure customers reached, not AI revenue, and RingCentral set the definition.
The sentence in our copy breaks off while comparing the figure to an earlier one, so we can't say what it doubled from. The wording matters more than the comparison. If a customer's whole contract counts once they buy any AI add-on, the number says little about how much AI is earning or whether customers use it. Total growth of 5.9% suggests AI attach is carrying the story. Ask any vendor quoting a similar metric for AI-specific revenue, the share of AI customers still active after renewal, and whether pilots count.
What should I ask my vendor before signing an AI renewal?
Ask whether you can export your accumulated context, meaning transcripts, indexes, knowledge connections and agent configuration, in a documented format, and what that costs, before you commit to anything.
This is the angle the roundup raises in its framing but doesn't test. Scott's introduction asks what it will cost to take your context with you when you leave. None of the vendor statements we read answers that. Zoom's self-hosting promise for Onyx is the closest thing to a portability commitment, and Scott himself says the test is whether "standalone and open" survives the integration roadmap. Get any such promise into the contract. A blog post or keynote is not enough.
Frequently asked questions
Is Onyx staying open source?
Zoom says so, along with model-agnostic and self-hostable. Scott says plenty of acquired open-source projects have quietly lost their openness, so he is waiting to see how it plays out.
Does the Microsoft exit offer affect Copilot support?
The source says Copilot teams are reportedly among those eligible. It says nothing on the effect for contact centre customers, so ask your account team directly.
Is Microsoft Contact Center Intelligence ready for production?
It launched in public preview, according to UC Today. Treat it as a pilot candidate and not a replacement plan.
