You don't build it. We deploy it.
Every CallSphere plan includes the build. Here is what happens after you book a demo — none of these steps land on your team.
Tell us how your calls work
Walk us through your call flows, FAQs, booking rules and escalation paths on a call. There is no builder to learn and no prompt to write.
We build and connect your agents
Our team designs your voice and chat agents and connects them to the calendar, CRM and phone system you already use through secure, permissioned access — no migration project.
Go live in about 24 hours
Most businesses are live in about 24 hours, and every plan starts with a 7-day free trial on your real calls.
We run and refine them
Your agents answer, book, verify and route around the clock within your configured workflows, and we refine them as your business changes.
Where CallSphere pulls ahead
Accessible to All Business Sizes
CallSphere serves businesses of every size on published plans starting at $19/mo. PolyAI focuses on large enterprises, so small and mid-market teams rarely have a practical way in. CallSphere deploys voice and chat automation for them too — answering, booking and updating systems end to end.
Live Before You Commit
CallSphere deploys in about 24 hours, and you can talk to a live demo agent right now. PolyAI’s enterprise sales cycle typically takes 6–12 weeks from initial contact to go-live.
Voice and Chat, Plus Workflow Automation, Not Voice Only
CallSphere combines voice agents and chat agents on a single platform with unified analytics and shared context — resolving the request and automating your business workflows end to end. PolyAI is voice-only, so businesses need additional vendors and integrations to cover chat, messaging, and the operational follow-through.
Transparent, Estimated Costs
CallSphere publishes its plan prices on its website, bills AI and telephony usage at cost with no markup, and gives you an all-in estimate for your call volume before you commit. PolyAI requires contacting sales for a custom quote, so you cannot evaluate cost without entering a sales process.
Where PolyAI wins
No tool wins every row. Here is where PolyAI is genuinely the stronger choice — so you can decide with eyes open:
- Deep enterprise contact-center expertise — PolyAI is purpose-built for very large, high-complexity voice deployments with dedicated solution engineering.
- Highly customized, white-glove voice assistants tuned to a specific brand and call flow, backed by a hands-on implementation team.
- A stronger fit for Fortune-500-scale call centers that want a bespoke build and have the budget and timeline for it.
What will it actually cost?
CallSphere Pricing
Published plans: Answer ($19/mo), Act ($49/mo), Orchestrate ($99/mo) and Custom Build ($149/mo), plus custom Enterprise. Answer answers common customer questions; booking and back-office workflows start on Act. AI and telephony usage is billed at cost with no markup (about $0.15/min inbound), and we give you an all-in estimate for your call volume before you commit.
PolyAI Pricing
Custom enterprise pricing only. Requires contacting their sales team, going through a discovery process, and negotiating a custom contract. Typically involves annual commitments and five-figure budgets.
Bottom line: PolyAI is designed for enterprises handling millions of calls. CallSphere publishes its plans instead: start on Answer ($19/mo) or Act ($49/mo, which adds booking and workflows), move up as what you need it to do grows, and pay AI and telephony usage at cost — with no annual contract required.
PolyAI pricing, feature, and compliance details reflect publicly available information as of June 2026 (HIPAA terms re-checked September 2026) and may change — always confirm current details on PolyAI's own site. Competitor HIPAA and BAA terms were re-checked on each vendor's own site in September 2026. Cost examples are illustrative models based on stated assumptions, not guarantees.
The Verdict
CallSphere is the better fit for businesses that want voice and chat agents deployed for them — answering calls and completing the work end to end — without an enterprise sales cycle or custom-quote pricing. PolyAI can be a fit for very large contact centers with dedicated budgets and long implementation timelines, but most businesses will find CallSphere faster to deploy, more affordable, and more versatile.
