The customer care accessibility your brand deserves

World leading brands need to reinforce their positions through always-accessible customer care. Making sure calls get straight through to service centers. And nobody is left hanging on the line.

At Sound of Data, we know how precious the human voice is to effective communication. And that there’s nothing worse than an unavailable or crackly line to spoil a customer care experience. Which is why we deploy ingenious use of our technology to prevent that from happening.

By rerouting your inbound calls outside of telecoms infrastructure, we bypass their capacity and routing limitations, raise the bar when it comes to quality and put you in full control of your call flow. Our service keeps every conversation flowing smoothly. All around the world.

"At Ticketmaster we regularly experience incoming call overloads when popular concerts go on sale. With Sound of Data’s Overload Solutions, we can plan and handle these peak calls ourselves even when there are 3,000 eager customers calling at the same time. There’s no other supplier who can offer such a reliable service so easily for us."
Reinout Al, Manager Contact Center, Ticketmaster
