How AI assistants recommend business phone systems

A small office that asks an AI assistant for a business phone system gets a short list of providers, and the list can differ from country to country. Here is what the assistants answered in every country the AIGROW Index asked, and what a provider can work on.

The first two rows are counts; the rows under them are medians over the ranked pages. Every question was asked without a location or a chat history.

Asked for business phone systems in 20 countries, ChatGPT, Claude and Gemini named about 23 providers per country, and 39% of those names came up only once. Each assistant builds its list from what is published about a provider. What a provider controls is that public record: its features, its pricing and its reviews.

The questions

What a customer asked, and who came first

One place of the 20, as an example: United States. Every place was asked the same questions in its own language, and its page in the Index has the full ranking.

  1. What is the best business phone system for a small business in the US?
  2. Our office in the US still uses old landlines, and we want to take calls on our laptops and cell phones too. Which business phone system would you recommend?
  3. Which VoIP phone provider would you recommend to a company with ten employees in the US?
  4. Which business phone system is easiest to set up for a small office in the US with no IT staff?

What to work on

What an owner can work on

No one can promise a place in an assistant’s answer. What an owner controls is what is published about the business, and these are the parts the questions above point to.

Replace the landlines

One question came from an office with old landlines that wants to take calls on laptops and cell phones too. Show how a call reaches each device, and what staff do to switch over.

Cover the ten-person company

Another asked about a company with ten employees. Say how plans and extra numbers work for a team that size, and how a new employee is added.

Setup without IT

One question asked for the easiest system for an office with no IT staff. Say how long setup takes, what you need to buy and who helps if something goes wrong.
