The Challenge
Your Phone System Shouldn’t Be
Holding You Back
Legacy Systems
Aging on-premise hardware is expensive to maintain, impossible to scale, and a single point of failure for your entire business.
Disconnected Tools
Separate systems for phones, routing, recording, and reporting mean duplicated effort, data silos, and constant workarounds.
No Visibility
Without real-time data on call volume, agent performance, and system health, you’re making critical decisions in the dark.
Meet Cloudspire Voice.

The Adaptability Difference
AI That Bends to
Your Business
Other providers pick one model for you, support a language or two, and shrug at the systems you already run. Cloudspire adapts to how you actually work: every major AI model, a voice for every audience, and connections into the tools you already own. It’s one of the most flexible AI voice platforms anywhere, which is why it fits every vertical we’re asked to serve, from a one-person shop that sets itself up online to an enterprise that wants us to build it all, white-glove.
Every Major Model
OpenAI, Anthropic, Google, and Amazon models all run on the platform. Pick the right brain per agent and per task and change it whenever you want; your plan sets which model tiers are available.
80+ Languages
Answer every caller in the language they actually speak: more than 80 languages across a library of 1,100+ voices, with agents that can follow a caller when they switch languages mid-call.
Connects to Anything
Native Salesforce, HubSpot, and Zoho, plus secure custom connections into any system you run, including the in-house and proprietary ones. Prompts and guardrails stay fully under your control.
Recently Shipped
What’s New
We’re constantly building. Here’s what we’ve recently added to the Cloudspire Voice platform.
iOS Mobile App
Native CallKit-integrated business phone for iPhone, with attended transfer, 3-way conference, parking, BLF, MMS picture messages, and one-scan QR onboarding. Available now on the App Store.
Cellular Callback
Place outbound business calls from the iOS app over your cellular line. The system rings your cell first, you press 1 to confirm, and bridges to the destination through the company trunk; outbound caller ID is your business number.
Start Online in Minutes
Buy online or start a 30-day free trial straight from the pricing page: pick a plan, choose or port your number, add phones, and your team approves it into service. No sales call required unless you want one.
Spire, Your AI Architect
Describe what you want in plain English and Spire designs it: menus, ring groups, hours, routing, even complete AI receptionists. Review the plan, approve it, and it’s live. Undo in one click.
Self-Service Number Porting
Keep the numbers your customers already know. Start a port from the portal, sign the LOA online, and watch live status updates at every step: no faxes, no phone tag with your old carrier.
Enhanced 911
Register your numbers for emergency dispatch with the address responders should see: set account-wide, override per extension, and update it yourself when you move. Safety that stays current.
Supervisor Whisper & Barge
Coach agents live without the caller hearing (*54), or join the call when a deal needs saving (*55). New-hire ramp-up and escalations get faster when help is one keypress away.
Three-Level Spam Protection
Pick Cautious, Balanced, or Maximum and let multi-provider spam intelligence score every inbound call; junk gets stopped or flagged before it ever rings your team.
What Customers Value
The moments that win people over
Illustrative examples drawn from real deployments, attributed by role and industry rather than by name.
We replaced a phone system nobody understood with one our office manager runs from a browser. Call flows changed in an afternoon, not a service ticket.
Every desk phone, the mobile app and the browser softphone ring together. Our field team stopped missing customer calls the day we switched.
Porting our numbers was the part we dreaded. It was handled for us, on the dates we were told, with the old system still running until the last minute.
Prefer the unfiltered version? Our customers leave their own words on Google.

Meet Spire, The AI That
Builds Your Phone System
Tell Spire what you want in plain English (“ring sales first, then everyone; after hours, take a message”) and it designs the change, shows you the plan, and applies it when you approve. It even drafts complete AI receptionists from a description. Configuration changes reversible in one click, and nothing changes on your system without your yes.
See What Spire Can BuildIllustrative Scenarios
Real Phones,
Really Answered
Situations businesses bring us, and what the phone system does about them. Illustrative scenarios, not customer statements.
Multi-site rollout
Forty extensions moved over a weekend, ported numbers and all, and the thing everyone noticed on Monday was that the missed-call report read zero.
Three-person shop
When all three people are already on calls, the AI answers the fourth, books the job, and texts the details, instead of the caller trying the next company on the list.
Seasonal spike
Volume triples for six weeks a year. The AI absorbs the overflow without a temp hire, and steps back out of the way when the season ends.
After-hours coverage
The line stops going to voicemail at 5 PM. Emergencies reach the on-call phone; everything else is booked into tomorrow with the caller's details already captured.
Front-desk relief
Routine questions (hours, directions, account balance, order status) are answered on the first ring, so the person at the desk is free for the person in front of them.
Remote and hybrid teams
Extensions follow people to the softphone on their laptop and the app on their phone. Callers dial one number; the business sounds like one building.
Call-center visibility
Supervisors see queues live, whisper coaching to a new agent mid-call, and pull the recording and transcript afterward without filing a request.
Compliance-minded industries
Recordings, transcripts, and a step-by-step record of every automated action, retained on your schedule, exportable when somebody asks.
Growing from one location to five
The second, third, and fifth office add extensions and a local number instead of a new phone system, and the dial plan stays one dial plan.
