Do I have to own a phone number to make calls?

Not at all. Outbound calls go through without buying any dedicated number, and you pay only the per minute rate.

Will my browser receive incoming calls?

Yes. Receiving calls just means adding a US/Canada digital number for $2.14 to $5/month.

Can I make a phone call from a library computer without installing anything?

Yes. Intercalling runs entirely in the browser, so you do not need to install software or have admin rights. This is ideal for library and other public computers where downloads are blocked.

Do I need my own phone number to call from a library computer?

No. Outbound calls through Intercalling do not require a phone number or a SIM card. You just open the browser and dial, paying per minute as you go.

Which browsers work on library computers?

Intercalling works in Chrome, Safari, Edge and Firefox. Library computers almost always have at least one of these installed, so you can start a call right away.

Is it private to call from a shared computer?

Calls are end to end encrypted. Because nothing is installed on the machine, you can close the tab when you finish and avoid leaving your call activity on a public computer.

How it Works

Library DialerReady

Making a Call from a Library or Shared Computer

A handful of quick steps keep your privacy protected and your audio crisp on any public workstation, all at cheap calling rates.

Plug in a Headset

Hook up a wired or USB headset so your conversation stays private and ambient noise stays low. Steer clear of the built-in speakers.

Grant Mic Access

Once the prompt shows up, allow microphone access, then double check the correct input device in your browser settings before you dial.

Sign Out and Wipe Data

After the call finishes, sign out of your Intercalling account and clear the browser data wherever the workstation permits it.

Quick Checklist

Sign in to Intercalling with Chrome, Firefox, or Safari
Carry your own headset to keep calls private
Allow microphone access and select the right device
Sign out and close the browser tab once you are done

Keeping Your Account Safe on Shared Devices

Easy habits that protect your account and your cheap calls on public workstations.

Skip Saving Credentials

Turn down any offer to save passwords or form data in the browser. Store those in a password manager on a device you own.

Two factor authentication adds an extra layer of protection to your account.

Reset Mic Permissions

After the call ends, revoke microphone access in browser settings if the machine seems sketchy. Shutting the tab generally clears any permissions still active.

Intercalling stores no microphone audio apart from the call logs tied to your account settings.

Network and Firewall Tips

Certain public networks limit voice apps. Here is how Intercalling gets around those restrictions.

Runs on Most Networks

Intercalling runs on WebRTC, so it links up across most public Wi-Fi networks and hotspots that allow ordinary browser traffic.

When Ports Are Blocked

Should outbound UDP or WebRTC be turned off, move to a different network or request temporary access from library staff. Intercalling switches to secure connections wherever they exist.

Nothing to Install

Because each call happens in the browser, there is no software to configure, which makes locked down public machines simple to use.

Why Intercalling Works Well on Public Computers

Intercalling connects your browser straight to the phone network so you can make and receive calls without any app. Backed by virtual numbers, , and real-time analytics, along with cheap per minute pricing, it fits professionals who work from anywhere.
