Voiso and Coldi: Bringing AI Voice Agents to the Contact Center

Coldi's AI voice agents now hold conversations that connect first time, in local numbers, across markets. That reliability comes from Voiso: the telephony, routing and call quality running beneath every agent.

Key Takeaways

  • Coldi’s AI voice agents run end to end on Voiso’s telephony, routing, and call quality instead of infrastructure Coldi had to build itself
  • Local numbers across a wide range of countries let Coldi’s agents place automated calls that land as local in each market
  • Geo-redundant infrastructure and call quality monitoring keep automated conversations stable across regions
  • The agents handle revenue-carrying calls: prospect qualification, lost-sale recovery, and routine customer conversations
  • Coldi’s engineering stays on the voice AI layer; the contact center layer is Voiso’s

AI voice agents are moving quickly from experiment to everyday operations. But a voice agent is only as capable as the platform it runs on. The telephony, the routing, and the call quality underneath decide whether an automated conversation connects at all, and whether it holds up across regions.

Voiso’s partnership with Coldi brings those two layers together. Coldi builds AI voice agents for businesses in call centers and fintech. Voiso provides the cloud contact center platform they run on.

What Coldi builds

Coldi builds AI voice agents for business, with a focus on call centers and fintech. Its agents handle the calls that carry revenue: qualifying prospects, recovering lost sales, and managing routine customer conversations. Rather than building communication infrastructure from the ground up, Coldi builds its service on an established contact center platform. That platform is Voiso.

One service, built on a platform designed to carry it

Coldi’s agents run on Voiso’s telephony, routing, and call quality. For the businesses Coldi serves, that means the automation sits on infrastructure built for contact center operations: local numbers across regions, stable call quality, and the routing logic that decides where each conversation goes.

Coldi keeps its focus on the voice AI. Voiso handles the contact center underneath.

Everything your team needs in one platform

Manage voice, SMS, messaging apps, AI-powered dialing, analytics, and reporting from a single contact center solution.

“Coldi is building the kind of service voice AI was supposed to deliver. Our job is to make sure the calls underneath it connect, in every market they operate in.”

Ivan Mitov, Partner Account Manager, Voiso

 

Why the platform underneath matters

An AI voice agent depends on connection quality. A call that drops, arrives from an unfamiliar number, or routes to the wrong place undoes whatever the automation was meant to achieve. Voiso runs on geo-redundant infrastructure with local numbers across a wide range of countries and monitoring built for call quality, so automated and human conversations alike stay clear and reliable.

The automation handles the routine, high-volume calls. Human teams stay focused on the conversations that need them.

What’s next

The partnership is at an early stage. As Coldi CEO Or Gold described it, Voiso provides the call center software and Coldi builds an end-to-end service on top, and he expects the partnership to be a turning point for Coldi’s growth. More on what Coldi’s agents can do on Voiso will follow.

The Challenge Brokerage technology providers sell completeness. A firm buying a CRM for a Forex or CFD operation expects the platform to carry the whole lifecycle: sales automation, KYC workflows, affiliate tracking, payment provider integrations, client portal management. Every gap in that stack is a reason for the prospect to look elsewhere. Voice was one […]

The Challenge Trading platforms compete on execution, and brokers judge them accordingly. Yet the moments that determine whether a trader stays with a brokerage mostly happen away from the order book: onboarding a new account, delivering a market alert while it still matters, answering a compliance request inside the window it allows. Those conversations have […]
