What is a cloud dialer, and does your team need one?
A cloud dialer is outbound calling software that runs on the internet instead of on a phone system in your office. What that means in practice, what it replaces, and when it is the right tool.
A cloud dialer is software for making outbound calls that runs on a provider's servers and is used through a web browser or a light app. The phone numbers, the connection to the phone network and the record of every call all live online. An agent needs a computer, a headset and an internet connection, and nothing else.
That sounds like a small change from a desk phone. In practice it changes who can be on your team, how fast they can start, and how much a manager can see.
How a call actually travels
When an agent clicks a number, the browser opens an encrypted voice connection to the dialer's servers using WebRTC, the same technology behind browser video calls. The dialer then places the call on the public phone network through a telecoms carrier, showing the caller ID number you chose. The person you are calling sees an ordinary call from an ordinary number. They cannot tell, and do not need to know, that the agent is in a browser.
What it replaces
Desk phones, and the cabling, power and configuration that come with them.
An office phone system, and the one person who knows how it is set up.
Copying phone numbers out of a spreadsheet: the leads list sits beside the dial pad.
End-of-week reports assembled by hand: every call is logged as it ends.
We go further into the hardware side in the desk phone is the last thing on your floor that needs a cable.
Cloud dialer, auto dialer, predictive dialer: the words
The terms get used loosely. Cloud dialer describes where the software runs. Auto dialer or power dialer describes how calls are placed, moving to the next number automatically. A predictive dialer rings several numbers per agent and connects whoever answers first, which raises throughput and also the risk of abandoned and silent calls, something regulators such as Ofcom in the UK watch closely. A click-to-call dialer, like ReachCalls, has the agent see the lead and start each call themselves, so nobody answers to silence.
When a cloud dialer is the right choice
Your team makes outbound calls for a large part of the day.
Agents work remotely, across more than one office, or in a different country from the people they call.
You want a local caller ID in the countries you call without opening an office there.
Headcount changes often, and adding a seat should take minutes rather than a hardware order.
It is less of a fit if most of your calls are inbound to a switchboard, or if you need phones in meeting rooms. Those are jobs for a business phone system, and we compare the two kinds of product in choosing calling software.
What to check before you trust one with your team
Audio quality on your own network, with your own headsets. Test it before the first shift.
Which countries it offers local numbers in.
How calls are billed. Billing by the second is fairer to short calls; see per-second vs per-minute billing.
What the admin can see, and whether agents can export or delete leads they should not.
ReachCalls is a cloud dialer for teams calling the UK, Ireland, the US, Canada, Australia, France, New Zealand and Singapore, with a local caller ID, a leads system and an admin panel. See the plans.
