What is the cheapest VoIP service for small business?

For small businesses watching every dollar, Intercalling keeps costs down because there is no hardware to buy. Everything runs in the browser, you pay only for the minutes you use, and capacity grows the moment your team does.

How does browser-based VoIP compare to desk phones?

A browser based line is far more flexible and far cheaper to run. Staff can dial from anywhere, CRM and AI tools plug in without friction, and you never pay to maintain or replace physical handsets.

Can I use AI with my business phone system?

Yes. Intercalling bundles AI Agents that field calls on their own plus an AI Copilot that guides your people live, capabilities that legacy phone systems simply do not include.

Is the connection secure for enterprise use?

Every call rides on WebRTC and the Twilio backbone, so voice traffic stays encrypted end to end with the security standards enterprises expect.

What are the cheapest VoIP phones for small business?

The most affordable VoIP phone for a modern small business is the softphone already sitting in your browser. Intercalling skips the cost of expensive handsets and turns the computers you own into a full enterprise telephone system.

What does the AI Copilot do during business calls?

The AI Copilot transcribes the conversation as it happens and proposes replies on the spot. Sales and support reps handle objections with confidence and nothing important slips past them.

Is this suitable for enterprise VoIP solutions?

Yes. Running on the Twilio backbone, Intercalling delivers enterprise grade reliability, numbers across 190+ countries, and AI Agents that scale to absorb heavy call volume on their own.

Do I need a phone number to make business calls?

No. Outbound calls on Intercalling need no phone number. You dial straight from the browser and pay per minute. You only need a number, a US or Canada digital line from about $2.14 to $5 per month, if you want clients to call you back.

Can a whole team use Intercalling without installing software?

Yes. It runs entirely in Chrome, Safari, Edge, or Firefox, so there is no app to download and no SIM card. Each team member simply signs in from a supported browser, which makes adding staff or remote contractors fast.

How does the per minute billing work for business calling?

Outbound calls are pay as you go and billed per minute, so you pay only for the time you spend on calls. There is no required monthly plan for outbound dialing, which keeps costs predictable for both small teams and high volume enterprise use.

Is Intercalling secure enough for client and partner calls?

Calls are end to end encrypted, which makes the service suitable for confidential client conversations, partner discussions, and international business outreach where privacy matters.
