The Problem
Why Houston Medical Practices Are Moving to an AI Answering Service
Houston is home to the Texas Medical Center, widely cited as the largest medical complex in the world, spread across the city's 713, 281, 832 and 346 area codes. A patient who reaches voicemail there has no shortage of other providers to call next. A traditional medical answering service can pick up, but it charges per call, locks you into a contract for HIPAA coverage, and relies on operators reading from a script with no access to your schedule or records. Retell operates under a signed BAA, checks your schedule and knowledge base to give real answers, and gets urgent messages to your on-call physician right away.

Capabilities
What Our Agent Does on a Call
Handles Patient Calls the Right Way:
It answers scheduling, prescription refill and billing questions using your practice's own information, with no phone tree to navigate.
It follows the escalation rules you set, so urgent messages reach your on-call physician instead of sitting in a queue.
When a patient needs a person, the agent warm-transfers them with the full conversation and caller details attached.
Answers from Your Practice's Knowledge Base:
It stays in sync with your knowledge base, so patients hear current answers about hours, providers and insurance accepted.
It can look up a patient's appointment or account mid-call and tailor what it says.
It connects to your scheduling and billing tools over secure webhooks while the call is live, and runs under a signed BAA with SOC 2 Type II controls.
Setup
Live in Four Steps
Step 1
Build
Set the agent up in a no-code dashboard or with the API, and point it at your scheduling system and practice FAQs.

Step 3
Deploy
Connect your practice line over SIP trunking or take a new number in a 713, 281, 832 or 346 area code, then go live on voice, SMS and chat.
Step 4

FAQ
Common Questions
Does Retell sign a Business Associate Agreement (BAA) for medical practices?
Yes. Any service that handles protected health information for a covered entity needs a signed BAA under HIPAA, and Retell signs one before your practice goes live, alongside SOC 2 Type II controls.
Can the AI agent make clinical decisions or triage patients?
No. The agent follows the escalation rules your practice sets. It does not diagnose, prescribe, or make clinical judgment calls. Anything that needs medical judgment gets routed to your staff or on-call physician.
What happens when a patient calls after hours with an urgent issue?
The agent asks the questions your practice defines, then follows your escalation rules to alert the on-call physician with the full transcript, instead of just taking a message or paging a callback number.
Does Retell work with Houston's 713, 281, 832 and 346 area codes?
Yes. You can connect an existing Houston-area line over SIP trunking or take a new number in any of the city's overlay area codes, 713, 281, 832 or 346, and the agent answers on that number 24/7.
What time zone does the agent use to answer calls for a Houston practice?
Houston runs on Central Time, and the agent answers on the first ring in that time zone around the clock, including nights, weekends and holidays, with no separate after-hours plan needed.
Does being close to the Texas Medical Center change what a Houston practice needs from an answering service?
It raises the stakes. Houston is home to the Texas Medical Center, widely cited as the largest medical complex in the world, so a patient near it who reaches voicemail has dozens of other providers within a few miles. Answering every call promptly and accurately matters more in a market with that much choice.
How much does a medical answering service cost for a Houston practice?
Retell is usage-based, from $0.07 to $0.31 per minute, with $10 in free credits to start and no contract, instead of the flat monthly retainer plus per-call and hold-time charges a traditional medical answering service usually bills.
