Google Voice, Zoom Phone, Webex or a dialer: choosing calling software
Business phone systems and outbound dialers look alike on a pricing page and behave very differently on a calling floor. A plain guide to which kind of tool fits which kind of team.
Search for calling software and you get very different products ranked side by side: Google Voice, Zoom Phone, Webex Calling, RingCentral and a long tail of sales dialers. They all make phone calls. They are not built for the same job, and picking the wrong category costs more than picking the wrong vendor within the right one.
Two kinds of product
A business phone system gives a company numbers, extensions, voicemail and call routing. Its centre of gravity is the organisation: who answers the main line, how calls move between colleagues, how the phone fits with meetings and chat. Google Voice, Zoom Phone, Webex Calling and RingCentral's core plans belong here.
An outbound dialer gives a team a way to call lists of people efficiently. Its centre of gravity is the list: who to call next, from which number, what happened, and how the team is doing. Sales-focused phone tools such as Aircall, JustCall and Kixie, and dialers like ReachCalls, belong here, each with its own focus.
The big names, briefly
Google Voice: a simple business line inside Google Workspace. Good for small offices, sold only in the countries Google supports, and not designed for outbound teams.
Zoom Phone: a full cloud phone system next to Zoom Meetings. Strong for companies already on Zoom; outbound contact centre tools are a separate product. More in Zoom Phone or a dedicated dialer.
Webex Calling: Cisco's enterprise cloud calling, usually bought through a partner. Best for large organisations replacing a Cisco phone estate. More in a Webex Calling alternative for small teams.
RingCentral: a broad business communications suite with phone, video and messaging, plus a separate contact centre line.
Sales-focused tools: built around CRM integrations and dialling modes, usually priced per user and paid by card.
Six questions that decide it
Which countries do you call, and can you get a local caller ID in each of them?
Where do your agents sit, and is the product sold and supported there?
Where does your list of leads live, and how many clicks is it from a lead to a ringing phone?
How long from signing up to an agent's first call: hours, days or a project?
How are calls charged: by the second, by the rounded-up minute, or an allowance you pay for whether you use it or not?
How do you pay: a card in US dollars, an invoice, or a local bank transfer?
Write your answers down before the first demo. Most bad purchases happen because the demo answered questions nobody asked.
Where ReachCalls fits
ReachCalls is for freelancers, sales teams and call centres whose work is outbound calling into the UK, Ireland, the US, Canada, Australia, France, New Zealand or Singapore. It runs in the browser, gives agents a local caller ID, keeps leads and notes beside the dial pad, and gives an admin one panel for agents and numbers. Calls are charged by the second from a monthly call credit, and you can pay by local bank transfer.
It is not a company switchboard and does not try to be one. If you need both, run both. If outbound is the job, compare our plans with the rest of your shortlist using cost per connected conversation rather than the headline seat price.
