AI voice agents that call every new lead within 60 seconds and qualify them before your team picks up
The agent initiates a call to every new lead within about a minute of form submission, so prospects are reached while intent is still high.
Voice agents hold natural back-and-forth dialogue, handle objections and keep qualifying even when a caller tests whether they are talking to a machine.
Appointments are booked directly into Google Calendar, and the agent schedules callbacks and reminders so no follow-up is forgotten.
Custom actions and pre-call webhooks let you inject live context, while native connections cover Gmail, Slack, Google Calendar, Zapier and thousands more tools.

Enterprise AI voice agents that work inside your phone system
Design AI agents for inbound and outbound calls without building a custom voice stack yourself.
Agents read and write Salesforce, HubSpot, Zendesk, Freshworks and more during the call, through 200+ integrations.
Keep your numbers and carrier thanks to built-in connections for Zoom, Five9, RingCentral, 8x8, Twilio, Telnyx, Vonage and Freshcaller, plus SIP setups.
Synthflow runs regional telephony infrastructure with SIP ladder, packet capture and quality scores for every call.
