Case Study: Hello Patient scales AI patient scheduling on Telnyx Voice AI
Key results
The challenge
In healthcare the phone is still the primary access point for care, but non-clinical staff field scheduling and referral calls between other tasks, and when they cannot keep up, calls go unanswered and appointments go unbooked. Hello Patient, a healthcare AI company founded in 2024, needed a dependable, scalable voice layer so its AI agents could turn live patient conversations into booked appointments without telephony becoming a bottleneck.
The solution
Hello Patient built its AI agents for voice, text, and web chat on Telnyx's Voice AI infrastructure, with integrations into EHR, CRM, and practice-management systems so the agents book appointments and update records in real time. Telnyx handles the voice, SMS, and routing layer with HIPAA-compliant AI voice agents, and CEO Alex Cohen said the team has grown without worrying about telephony scaling.
“We're seeing more appointments being booked with fewer staff needed to run call centers and traditional phone lines.”

The results, in context
Hello Patient reports its customers see measurable results: double-digit percentage lifts in appointments scheduled, described as around 20% more appointments booked, and 25% to 30% conversion rates when reaching out to referred patients to get them scheduled. In some cases practices moved from 20-30% of calls going unanswered to zero unanswered. Hello Patient has powered more than 5 million patient conversations in under two years on the Telnyx-based platform. Figures are quoted from Telnyx's published customer story (dated Jun 24, 2026).
