Synthflow
Synthflow is an enterprise voice AI platform for automated phone calls, with a visual Flow Designer, automated testing and its own telephony network.
About this tool
Synthflow builds voice AI agents for enterprises that automate phone calls. Its BELL framework, short for Build, Evaluate, Launch, Learn, structures the agent lifecycle into a repeatable process built into the platform, so organisations can deploy agents faster and improve them over time.
Agents are designed in a visual Flow Designer that encodes business logic step by step and connects to APIs. A Test Center places simulated calls and scores them for accuracy, answer quality and compliance with your KPIs before customers are involved. Calls run over Synthflow’s own telephony network, SIP trunking or approved enterprise telephony, with integrations for CRMs, calendars and contact-centre stacks.
What you can do
Visual Flow Designer
Define each step of the call logic and connect APIs without guesswork.
Test Center
Simulated calls check accuracy, quality and compliance before launch.
Native telephony
Run calls on Synthflow’s network, through SIP trunking or enterprise telephony.
Enterprise integrations

Who is it for?
- A contact centre automates first-line calls with escalation paths to human agents.
- A healthcare network handles appointment scheduling calls integrated with its calendar system.
- An enterprise tests a new call flow in simulation before routing live traffic.
Before you choose
Enterprise deployments involve implementation and security reviews, which lengthen time to launch.
