How it works

From the customer’s call to the right person—without the customer thinking about any of it.

IronSpark handles the communications logic behind the scenes. Your team uses supported endpoints; your customers use the business number they already know.

01 · DISCOVER

We map your call flow

Who answers first? Who is backup? What happens after hours? Which people work remotely?

02 · TRIAL

We build a 10-day trial

The trial lets you experience the routing and workflow before committing to a larger change.

03 · CONNECT

We configure supported endpoints

For desk users, IronSpark supports Grandstream VoIP desk phones. For mobile and computer users, Zoiper softphones keep the same business communications system available away from the desk.

04 · OPERATE

IronSpark manages the platform

Routing, monitoring, infrastructure and ongoing configuration remain our responsibility.

What happens when a call comes in?

Business numberThe customer calls the company, not an employee’s private number.
RulesBusiness hours and routing determine the first destination.
PeopleThe appropriate person or group rings.
FallbackOverflow, on-call behavior or voicemail handles unanswered calls.
Change without disruptionWe can change the internal path while the public number remains the same.
