New capabilities will turn inbound calls into confirmed appointments and give HubSpot's AI agents access to richer customer context

ATLANTA, Sept. 9, 2026 /PRNewswire/ -- CallRail, the AI-powered lead engagement platform, today announced the release of two new enhancements to its HubSpot integration. Voice Assist Scheduling enables CallRail's AI voice agent to book meetings directly on HubSpot calendars while a caller is still on the phone. Separately, the CallRail MCP will be available in HubSpot's new Agent Hub, giving HubSpot's AI agents direct access to CallRail call data and conversation insights. CallRail will demonstrate both beta capabilities at HubSpot's annual UNBOUND conference, where attendees can connect with the team and learn more.

Voice Assist Scheduling integrates CallRail's AI voice agent directly with a business's HubSpot calendar and CRM workflow. During a live call, Voice Assist can:

• Schedule in real time: Check real-time availability on the appropriate HubSpot calendar, offer available meeting times, and confirm the appointment while the caller remains on the line.
• Automate follow-up: Write the completed booking to the HubSpot contact and deal records, removing the manual step between lead capture and scheduling, where small businesses often lose their speed-to-lead advantage.

CallRail is also bringing phone conversation data into HubSpot's agentic CRM environment through the CallRail MCP. Available in beta through HubSpot's new Agent Hub, the MCP gives HubSpot AI agents direct access to CallRail call data and conversation insights. This provides richer customer context for future interactions and helps businesses deliver a more connected experience without requiring customers to repeat information they have already shared.

Together, Voice Assist Scheduling and the CallRail MCP extend CallRail's HubSpot integration from capturing and organizing lead information to taking action on it. More than 4,500 CallRail accounts are already connected to HubSpot, demonstrating the integration's growing role in how businesses manage customer intake and follow-up. Voice Assist Scheduling advances that workflow by helping businesses move from an inbound call to a confirmed appointment without a manual handoff or callback delay.

"The gap between capturing a lead and scheduling the next step is where many small businesses lose valuable time and opportunities," said Marc Ginsberg, CEO of CallRail. "By combining CallRail's phone conversation intelligence with HubSpot's CRM and scheduling capabilities, Voice Assist can move a caller from the first conversation to a confirmed meeting without waiting for manual follow-up. We're excited to demonstrate this next step in our work with HubSpot at UNBOUND and show businesses how they can create a more connected path from the first call to the booked meeting."
