What happened
Enterprise voice AI company Regal Voice has integrated its autonomous AI voice agents into Five9's contact center platform through Five9's AI Agent Connect program. The integration allows Five9 customers to trigger follow-up calls or texts from Regal's AI agents automatically after a call event, with call records and contact history flowing between the two systems. Regal's software can also score contacts for intent and route high-intent leads directly into Five9 outbound campaigns without manual intervention.
Why it matters
The partnership expands Regal's reach into Five9's customer base of more than 3,500 enterprises across more than 140 countries. For contact centers in regulated industries like healthcare, insurance, and education—where Regal already operates—the integration removes manual queueing steps and lets AI and human agents start with full call history. Regal claims a 99.5% resolution rate without human handoff, so the pairing may reduce operational friction for enterprises managing high call volumes.
What to watch
Regal has raised $83 million to date, most recently $40 million in October 2024. Five9 reported strong results on April 30, with subscription revenue growth accelerating for a second consecutive quarter and the company raising its full-year outlook; the stock rose about 18% on those results. Both companies are signaling momentum in agentic contact center software.

Regal Voice's integration into Five9's platform reflects a broader industry shift toward agentic software in contact centers. Five9, which serves over 3,500 enterprises globally, has positioned itself to support third-party AI vendors through its AI Agent Connect program, signaling that the contact center market is moving away from monolithic solutions toward modular, AI-driven workflows. Regal's entry into this ecosystem is significant because the company already operates in highly regulated sectors—healthcare, insurance, and education—where compliance and script adherence are critical. By embedding into Five9's infrastructure, Regal gains access to a much larger addressable market without requiring customers to rip-and-replace their existing platforms.
The technical design of the integration emphasizes seamlessness: call data flows automatically between systems, history persists across human and AI handlers, and high-intent leads route to campaigns without manual intervention. This automation layer is attractive to enterprises because it reduces operational overhead and removes handoff friction—two persistent pain points in contact center operations. Regal's claimed 99.5% resolution rate without human handoff, combined with data from over 500 million calls, positions it as a credible vendor in this space. Five9's own momentum—subscription revenue accelerating for a second consecutive quarter and the stock rising 18% on April 30 results—suggests the market is rewarding companies that successfully integrate agentic capabilities into their platforms.
