The problem
Carrying voice over packet networks meant solving jitter, packet loss, routing and reliability at carrier scale.
The innovation
A large portfolio of patented methods for delivering reliable voice and multimedia over IP networks.
How it worked
Packetised audio with routing, buffering and quality management replaces a dedicated circuit for each call.
Why it mattered
Long-distance calling costs collapsed; audio and video calling became a default expectation.
The legacy
Croak's text-to-donate system later channelled hundreds of millions in disaster relief giving by SMS.
You use this today
Every internet call and video meeting.
