SmarterHello: 1,600 concurrent Voice AI calls

Engagement context

SmarterHello is a Voice AI SaaS platform — and a Foundation5 client product engagement. The brief was not to install a third-party bot shelf. It was to build production-ready cross-channel agents (phone, SMS, email, webchat) capable of high concurrent inbound volume with live CRM context.

The headline capacity — up to 1,600 simultaneous customer calls, 20+ languages on a unified knowledge base — only matters because escalation, permissions, and Salesforce connectivity were designed as product requirements.

Architecture that protects trust

Foundation5 provided technology strategy, Voice AI architecture, Twilio/SignalWire telephony integration, and Salesforce Agentforce connectivity. Knowledge ownership, transcript retention, and human handoffs with full context were specified before scale tests — the opposite of demo-first launches that reverse when CSAT drops.

This engagement informs how we advise other organizations: start with coverage and response-time outcomes, connect agents to CRM safely, and measure containment with CSAT. See Voice AI consulting and customers want answers, not support.

• Up to 1,600 simultaneous customer calls supported
• 20+ languages on a unified knowledge base
• CRM-connected agents with human escalation paths
• Production architecture the product team could extend

Lessons for Voice AI buyers

Concurrent call claims without permission models and escalation design are marketing. Ask vendors — and your own teams — who owns knowledge updates, what CRM fields AI may write, and how humans receive transcripts. Schedule a consultation to apply the same checklist to your contact paths.
