A Phone System for Virtual Assistants That Works in the Browser

In short

StartACall gives virtual assistants and the people who hire them a full phone system that runs in any browser, with no app, no SIM card, and no desk phone. Make outbound client calls with no phone number on pay as you go per minute billing, and add a US or Canada number which runs between $2.14 and $5 monthly when your VA needs to receive calls too.

Why a browser based system fits virtual assistant work

Virtual assistants often work from anywhere, switch devices, and handle calls for more than one client. StartACall runs in Chrome, Safari, Edge, and Firefox, so a VA can place a call from a laptop in one country and a tablet in another without installing software or buying hardware. There is no SIM card to manage and no number to port, which keeps onboarding to minutes instead of days.

Outbound calls do not require you to own a phone number, and you pay per minute as you go. That suits the uneven call volume of assistant work, where one week may be heavy with appointment confirmations and the next nearly silent. You fund the account and only spend on the minutes you actually use.

Receiving calls and keeping client lines separate

When a client wants their VA to answer incoming calls, you add a dedicated US or Canada digital number for between $2.14 and $5 a month. Each number can act as a separate inbound line, so a virtual assistant supporting several clients can keep each business reachable on its own number rather than mixing everything into one personal mobile.

Because the number is digital and tied to the browser session, a VA can answer from any signed in device. This avoids sharing a personal cell number with clients and makes it simple to hand a line off or retire it when an engagement ends.

Privacy and international reach

Calls are end to end encrypted, which matters when assistants discuss schedules, payments, or customer details on behalf of a business. The browser based setup also makes international calling practical, so a VA based overseas can call clients and their customers in the US or Canada at per minute rates without roaming charges or a local SIM.

Frequently asked questions

Can one virtual assistant manage phone lines for several clients?+

Yes. You can add a separate US or Canada digital number for each client at about $2.14 to $5 per month per number, so every business stays reachable on its own inbound line. Outbound calls do not need a number at all, so a VA can dial out for any client right away.

Does the virtual assistant need to install anything or buy a phone?+

No. StartACall runs entirely in the browser on Chrome, Safari, Edge, or Firefox. There is no app download, no SIM card, and no desk phone, so a VA can start calling from a laptop, tablet, or any signed in device.

How is calling billed for a virtual assistant setup?+

Outbound calls are pay as you go, billed per minute, so you only pay for the talk time you use. The only fixed cost is the monthly fee, about $2.14 to $5, for each digital number you add to receive inbound calls.

Is it safe to discuss client information on these calls?+

Calls are end to end encrypted, which helps protect the schedules, payment details, and customer information a virtual assistant often handles. Using a dedicated digital number per client also keeps your personal phone number private.
