How to Call from a Library or Shared Computer

Follow simple steps to protect your privacy and get crystal clear calls from any public workstation.

1

Use a Headset

Plug in a wired headset or USB headset to keep audio private and reduce background noise. Built-in speakers are not recommended.

2

Allow Mic Access

When the browser asks, allow microphone access. Verify the correct input device in browser settings before you call.

3

Sign Out and Clear Data

Finish the call, sign out of your StartACall account, and clear browser data if the workstation provides that option.

Quick Checklist

  • Sign in to StartACall in Chrome, Firefox, or Safari
  • Use a personal headset for privacy
  • Allow microphone access and select the right device
  • Sign out and close the browser tab when done

Privacy and Security on Shared Devices

Practical tips to keep your calls and account secure when using public workstations.

Do Not Save Credentials

Choose not to save passwords or form data in the browser. Use a password manager on your own device instead.

Two factor authentication is supported for extra account security.

Clear Mic Permissions

After the call, revoke microphone access in browser settings if you do not trust the machine. Closing the tab often clears active permissions.

StartACall does not store microphone audio outside of call logs tied to your account settings.

Network and Firewall Considerations

Public networks sometimes limit voice applications. Here is how StartACall handles network constraints.

Works on Most Networks

StartACall uses WebRTC which works on most public Wi-Fi networks and hotspots that allow standard browser traffic.

Blocked Ports

If outbound UDP or WebRTC is blocked, try switching to a different network or ask the library staff about temporary access. StartACall can fallback to secure connections when available.

No Install Required

Because calls happen in your browser, there is no software to install which simplifies use on locked down public machines.

StartACall bridges your browser to the phone network so you can place and receive calls without apps. Features like virtual numbers, AI agents, and real-time analytics make it ideal for professionals who need to work from anywhere.
