PolyAI Alternatives in 2026: 6 Options for Contact Centers

A contact center leader shortlisting PolyAI is usually buying an outcome, not a toolkit: someone else's team builds the agent, tunes it and answers the pager. That narrows the field quickly, because most of the alternatives sell a builder and expect you or a systems integrator to do the work.

All vendor facts below come from each vendor's own website, product documentation, trust center or status page, checked in October 2026. "Not documented" means we did not find it on the pages we checked, not that the capability does not exist.

What does PolyAI offer contact centers as of October 2026?

PolyAI sells voice agents two ways: a managed service it describes as "design it, build it, run it on our own models," and a self-serve Agent Studio with a developer kit and REST APIs. The platform is hosted on AWS, and PolyAI states data residency in the US, UK, EU and APAC with no cross-region transfer. Australia is not named as a specific region.

Its integration page claims more than 130 integrations. The telephony list includes 3CX, Amazon Connect, Avaya, Cisco, Dialpad, Five9, Genesys, GoTo, Mitel, NICE, RingCentral, Talkdesk, Twilio, Vonage and Zendesk Talk, and the docs carry step-by-step guides for Genesys Cloud BYOC, Five9, NICE CXone, Amazon Connect, Twilio and custom SIP. PolyAI lists ISO 27001, SOC 2 Type II, HIPAA, PCI DSS, Cyber Essentials Plus and GDPR, and its homepage claims 99.994% uptime over the trailing twelve months.

Pricing for the full platform is per minute but unpublished. The one public number is for PolyAI's raw model API, at 2 cents per connected minute, which is a developer product rather than the managed service a contact center would buy.

Why do contact centers look for PolyAI alternatives?

Contact centers look past PolyAI when their requirements sit outside its published footprint: infrastructure they must run themselves, a named Australian region, an outbound dialer it does not list, or a budget model that needs a public rate card. None of these is a flaw in PolyAI's product. They are boundaries, and they matter to specific buyers.

• No on-premise option. PolyAI's homepage, security page, docs and compliance page describe AWS hosting and no on-premise or private-cloud deployment. What to do: if your security team requires processing inside your own data center, start with vendors that document on-premise deployment (Trillet, Kore.ai, Cognigy).
• Australia is not named. "APAC" covers a lot of territory. What to do: if an Australian regulator, board or customer contract requires onshore processing, ask PolyAI to name the region in writing, and compare it with vendors that publish a Sydney or Australian environment.
• Outbound dialers. PolyAI's telephony list centers on CCaaS and PBX platforms, and ViciDial does not appear on it. What to do: collections and sales floors running ViciDial should test that integration specifically rather than assume a generic SIP trunk will cover it.
• Custom SIP limits. PolyAI's docs state that custom SIP is IPv4-only, caps allow-lists at 10 entries and accepts CIDR blocks no larger than /18, and some accounts see SIP setup as "coming soon." What to do: send your network team that docs page before the commercial conversation, not after.

How do the six PolyAI alternatives compare?

The six alternatives split into three operating models: a vendor-managed service (Trillet), builder platforms you or a partner configure (Parloa, Kore.ai, NiCE Cognigy), and hyperscaler services you assemble yourself (Google, Amazon Connect). The table shows where each one stands on the criteria that most often decide a contact center shortlist, as of October 2026.

A blank on a vendor's website is not proof of absence, so treat "not documented" cells as questions for the sales call. For a broader side-by-side that includes agency platforms, see the voice AI platform comparison hub.

What are the best PolyAI alternatives for contact centers?

The best PolyAI alternative depends on which constraint pushed you off PolyAI, because each one wins a different contact center. The short profiles below say what each one does well, where it is weaker than PolyAI, and the situation in which it belongs at the top of the list.

Trillet: managed delivery with on-premise and legacy dialers

Trillet is the closest match to PolyAI's operating model: Trillet's solution architects design, build, deploy and manage the implementation, so the contact center needs no internal engineering team. The difference is where it can run and what it connects to. Trillet deploys in the cloud, in a private cloud or VPC, or fully on-premise via Docker, and connects the AI agent natively to ViciDial and, through custom integration scoped per engagement, to Avaya, Cisco CUCM, Mitel and Asterisk-based PBXs over SIP trunks and CTI bridges. Its ViciDial integration for call centers is production-proven, which matters for outbound and collections floors.

Two further differences: customers can choose their own text-to-speech, language model and telephony providers rather than running on the vendor's models, and Trillet is headquartered in Australia with onshore engineering and support. Enterprise deployments are available in any region by agreement, and in-country model hosting is available by agreement. Pricing is custom per engagement, as of October 2026.

Pick it if: you want PolyAI's hands-off delivery but need on-premise deployment, ViciDial or a legacy PBX connected to the AI agent itself.

Parloa: a builder suite with deep EU compliance

Parloa sells a platform (Agent Builder, Performance Lab, Lens and related tools) that your team configures, with pricing set through a joint business case. It lists more than 50 native integrations, including Genesys, Amazon Connect, Cisco, Avaya, Five9 and Talkdesk, plus Salesforce, ServiceNow and SAP. Its trust center lists ISO 42001, DORA and the EU AI Act alongside ISO 27001, SOC 2, PCI DSS and HIPAA, the deepest stated EU regulatory coverage in this group.

Parloa describes built-in data residency but names no regions, documents no on-premise option, and does not list NICE or Twilio as native connectors. Pricing is quote-only, per minute for voice, with outcome-based pricing "when it makes sense."

Pick it if: you operate under EU financial or AI regulation and have a team that wants to build and tune agents in-house.

Kore.ai: the widest deployment choice among builders

Kore.ai's trust center lists multi-tenant SaaS, on-premise and single-tenant private cloud, and its status page shows an APAC (Sydney) region. It names NICE CXone, Five9, Talkdesk, Genesys and Amazon Connect, and offers its own voice gateway and bring-your-own SIP. Delivery runs through systems integrators such as Accenture, Cognizant and Infosys, and through the AWS and Azure marketplaces.

The trade-off against PolyAI is delivery: Kore.ai is a platform, and someone (your team or an integrator) builds on it. Avaya, Cisco and Mitel were not found in its documentation, and pricing is quote-only.

Pick it if: you need on-premise or a published Sydney region and already work with one of its integrator partners.

NiCE Cognigy: CCaaS reach plus an Australian region

NiCE Cognigy, owned by NICE since September 2025 and sold both standalone and inside CXone Mpower, offers shared SaaS, dedicated SaaS and on-premise installation on Kubernetes. Its status page lists Australian SaaS and voice gateway environments. It connects to Avaya, Amazon Connect, Genesys, NiCE CXone, Five9, Twilio and RingCentral, and says it can work with any SIP trunk provider.

Cognigy is a low-code studio sold through partners; no managed service was found. Its own prerequisites page warns that non-managed Kubernetes distributions need "significant additional configuration effort," so on-premise means your team runs the cluster. Cisco and Mitel were not found.

Pick it if: you already run NICE CXone, or you need an Australian region and have Kubernetes skills in-house.

Google: Gemini Enterprise for CX (formerly Contact Center AI)

Google's offering is now called Gemini Enterprise for Customer Experience, with CX Agent Studio as the builder, and it is the clearest-priced option here at $0.50 per voice session ($0.40 on a three-year plan), with sessions over five minutes billed at $0.0025 per second. The catch for Australian buyers is hosting: CX Agent Studio runs only in the US and EU multi-regions, and it is not on Google's IRAP service list, although older Dialogflow and CCAI components are. Pick it if: you are a Google Cloud shop outside Australia with engineers to build and integrate.

Amazon Connect: AI priced into the channel rate

Amazon Connect (now marketed as Amazon Connect Customer) charges $0.038 per voice minute with AI self-service included and telephony extra, with no seat licenses, as of October 2026. It offers agentic voice in the Asia Pacific (Sydney) region, and AWS lists Connect as in scope for IRAP at the PROTECTED level, which matters for Australian government work.

It is a build-it-yourself AWS service. Its connector for on-premise Avaya, Cisco UCCE and Genesys Engage feeds conversational analytics only, not AI self-service, and third-party AI agents join through an API-only integration. Prices "may vary by region."

Pick it if: you are moving the whole contact center to AWS, serve Australian government, and have the engineering team to build on it.

Where does Trillet fall short of PolyAI?

Trillet does not beat PolyAI on integration breadth, attestations or published hosting, and a fair comparison should say so. PolyAI documents step-by-step connectors for Genesys Cloud, NICE CXone, Five9 and Amazon Connect; Trillet has no native Genesys or NICE connector; integration with either is custom work scoped per engagement, so a contact center built on either should scope it before shortlisting.

PolyAI also lists PCI DSS, HIPAA and Cyber Essentials Plus on top of the SOC 2 Type II and ISO 27001 that Trillet holds, and it publishes an APAC region where Trillet's residency is set by agreement rather than published. Neither publishes a platform price. What to do: if your requirements are a CCaaS connector plus PCI scope, PolyAI is the stronger fit on paper; if they are on-premise deployment, ViciDial or a Mitel or Cisco CUCM PBX connected to the AI agent, test Trillet.

How should a contact center choose between them?

Decide the operating model before comparing features, because it determines your headcount more than any line in the table. If nobody on your team will build or maintain agents, your realistic options are PolyAI and Trillet. If you have a CX engineering team, the builders and hyperscalers open up, and price transparency starts to favor Google and AWS.

Then filter on the constraint you cannot negotiate: on-premise processing, a named Australian region, a specific attestation such as IRAP or PCI DSS, or a dialer such as ViciDial. That usually leaves two or three names. Our best voice AI for contact centers guide covers a wider field, including developer platforms.

To scope a managed deployment on your own PBX or ViciDial environment, talk to Trillet's enterprise team.

Frequently Asked Questions

What is the best alternative to PolyAI?

It depends on what you are replacing PolyAI for. For the same vendor-managed model with on-premise deployment and ViciDial support, look at Trillet; for on-premise plus a Sydney region on a builder platform, Kore.ai or NiCE Cognigy; for public per-minute pricing with AI included, Amazon Connect.

Does PolyAI offer on-premise deployment?

Not on the pages we checked in October 2026. PolyAI's security page states the platform is hosted on AWS, and its docs and compliance pages describe no on-premise or private-cloud option. Ask PolyAI directly if you need a dedicated environment.

How much does PolyAI cost?

PolyAI does not publish platform pricing; its pricing page says the platform is billed per minute and asks buyers to talk to its team. Its raw model API is public at 2 cents per connected minute, but that is a developer product, not the managed contact center service.

Is PolyAI hosted in Australia?

PolyAI lists data residency in the US, UK, EU and APAC with no cross-region transfer, but does not name Australia specifically. Cognigy, Kore.ai and Amazon Connect publish Australian or Sydney regions; Trillet offers data residency by agreement.

Which PolyAI alternatives work with ViciDial?

Of the vendors in this comparison, Trillet is the one that documents a production ViciDial integration. We did not find ViciDial named on the PolyAI, Parloa, Kore.ai, Cognigy, Google or AWS pages we checked.
