Missed calls have long been the bane of sales teams. CallRail, best known for its lead engagement platform, thinks it’s found the fix: an AI assistant that never clocks out.

At HubSpot’s INBOUND event, CallRail announced an expanded integration with HubSpot that brings insights from its recently launched Voice Assist directly into the CRM. The update means that leads captured and qualified by Voice Assist now automatically flow into HubSpot, giving sales and marketing teams a unified, 24/7 picture of customer activity.

Voice Assist: A Call Handler That Works Nights

Launched in July, Voice Assist captures and qualifies leads around the clock, handling conversations with a human-like cadence. For companies that can’t afford to lose high-intent prospects after hours, it’s a safety net—and one that pairs neatly with HubSpot’s follow-up workflows.

CallRail says the HubSpot integration makes this AI assistant more valuable, since every conversation summary, qualification insight, and customer data point is synced automatically. The result: fewer gaps, faster follow-up, and stronger attribution for ROI-minded marketers.

On the Ground at INBOUND

At INBOUND, CallRail showed off live demos of Voice Assist, letting attendees hear for themselves how the system qualifies leads and drops conversation data into HubSpot. Customers like Mid-Atlantic Builders are already seeing an impact. “Missed calls are virtually nonexistent now,” said Bradford Smith, VP of sales and marketing at the firm. “And the ability to store full conversation summaries in HubSpot will only give us deeper insights.”

Recognition in the HubSpot Ecosystem

The announcement comes as CallRail secures a spot—for the second year running—on HubSpot’s Essential Apps for Sales list, a curated group of integrations that help sellers move faster and smarter. Angela O’Dowd, VP of partner ecosystem at HubSpot, called Voice Assist “an innovative solution that ensures every lead is captured, qualified, and seamlessly integrated into our CRM.”

Why It Matters

The integration underscores a broader trend: CRMs are no longer passive data stores, but living systems fed by AI-powered tools that catch leads before they slip through the cracks. Rival platforms like Salesforce and Zoho have been embedding conversational AI into their ecosystems; HubSpot is leaning on app partners like CallRail to deliver similar value without overhauling its own core software.

For agencies and small-to-midsize businesses in particular, the promise is compelling: no more missed leads, no more guessing whether the follow-up data is complete, and no more disconnect between marketing attribution and sales execution.
