Voice
Inbound, outbound and multilingual — without a calling floor.
Automate inbound support, outbound campaigns and AI conversations across every channel. Natural voices, CRM handoff, and conversation intelligence on every call.
The pain
What is leaking today
Missed calls are missed revenue
After hours, the line dies.
IVR that people hate
Press 1 forever.
No brief for the human
Escalation is a cold transfer.
How Spark solves it
The system, not another tool
Voice that can act
Answer, qualify, book, FAQ.
Same knowledge as chat
CX OS, not a separate bot.
Escalation with a story
The agent already captured intent.
