AI Voice Agents - Houston, TX
MD Anderson's patient access center handles roughly 22,000 inbound calls a week across 700-plus physicians. Memorial Hermann routes scheduling across 17 hospitals on Epic Cadence. Houston Methodist runs a centralized contact center for eight hospitals and 30-plus clinics. The hold queue past four minutes correlates with a measurable abandonment rate and a referral leak to nearby systems.
When the next named storm hits the Gulf Coast, CenterPoint Energy's outage line takes hundreds of thousands of calls in a single afternoon. The Beryl event in July 2024 made the limits of the existing IVR visible to anyone who tried to report a downed line that week. Port of Houston dispatch and oilfield-services call lines run their own surge patterns tied to vessel arrivals and rig schedules.
Voice agent builds for Houston are scoped and priced based on call-flow complexity and the systems we connect to.

The Texas Medical Center is the largest medical complex on the planet. 60-plus member institutions covering 2.1 square miles in the middle of Houston. MD Anderson, Memorial Hermann, Houston Methodist, Texas Children's, Baylor College of Medicine, and the rest all operate patient access centers with their own scheduling, referral, and clinical-trial intake workflows. Most of them run on Epic Cadence with regional staffing in Houston, San Antonio, and Austin.
Spanish-preferred callers make up roughly 30 percent of TMC inbound volume. Bilingual schedulers are in short supply across Harris County, and the wage premium for fluent English-Spanish staff has run ahead of wage growth in the rest of the patient access role family. The math has been pushing systems toward automation for two years; the technology now meets the bar.
CenterPoint Energy serves roughly 2.7 million electric customers across the Houston metro. A typical clear-weather week handles thousands of outage and billing inquiries; a named-storm week handles hundreds of thousands. The Beryl event in 2024 produced multi-hour hold times that became a Texas PUC docket. Better voice automation is on the table because the operational status quo failed in public.
Port of Houston is the largest export port in the United States by tonnage. Dispatch lines for trucking, drayage, and Customs brokerage operate around the clock with strict appointment windows for container pickup at Bayport and Barbours Cut terminals. A missed appointment cascades into demurrage charges and rebooked vessel slots. The call mix is mostly structured: truck number, container ID, appointment window, gate code. Exactly the shape a voice agent handles end-to-end.
Oilfield-services dispatch at Halliburton, Schlumberger, and Baker Hughes covers a service-call pattern that peaks around rig schedules and shifts with West Texas Intermediate price moves. Phillips 66 and the rest of the Energy Corridor majors run customer-service lines for retail fuel cards and commercial-account billing where the routine queries dominate the call mix.
We build voice agents that hold under storm-load surge, handle English and Spanish without a handoff penalty, integrate with Epic Cadence for healthcare scheduling, and route cleanly to your human staff for the calls that need them.
Twilio or Telnyx number routes incoming calls to a Vapi or Retell AI orchestrator on the first ring. Deepgram Nova-2 streaming STT with automatic English-Spanish language ID, intent classification in the first 8 seconds, and a structured handoff to your human team when escalation rules trigger.
Appointment reminders for TMC clinics, no-show recovery for specialty practices, clinical-trial recruiting follow-ups at MD Anderson. Voicemail detection on the first 4 seconds of answer audio. Texas Do Not Call list and federal DNC checked pre-dial. TCPA-aligned consent capture.
Real-time provider availability reads across multi-hospital systems via Epic App Orchard APIs over the customer's interconnect. Atomic appointment write-back with idempotency keys tied to call session IDs. Epic-native SMS confirmation triggers from the booked record.
Salesforce Service Cloud, HubSpot, ServiceNow, and custom dispatcher systems for Port of Houston drayage. Caller identification by inbound number lookup pulls the contact record before the agent speaks. Tool calls wrapped in circuit breakers so a backend slowdown does not cascade.
When the agent escalates, it calls your on-duty staff member, summarizes the caller context in 2 to 3 sentences over the wire, then bridges the caller. The human is briefed before saying hello. For bilingual flows, the transfer routes to a fluent Spanish scheduler.
Every call gets a timestamped transcript, audio recording in an S3 bucket inside your AWS account with KMS keys you control, and a structured outcome record (booked, escalated, abandoned). CloudWatch dashboards for active calls, p50 and p95 latency, and tool-call error rate.
Four call-flow patterns that recur across Houston engagements. Each has its own integration list, compliance bar, and load shape.
MD Anderson, Memorial Hermann, Houston Methodist, Baylor St. Luke's, and Texas Children's all run patient access centers on Epic Cadence. We integrate through Epic App Orchard with OAuth 2.0 against the customer's interconnect, read provider availability across the requested clinic, present the next three slots that match the caller's preferences, write the appointment back atomically, and trigger Epic-native SMS confirmation. Bilingual English-Spanish flow with code-switch fallback to a human scheduler. HIPAA-relevant PHI encrypted at rest with BAA-covered vendors only.
CenterPoint Energy, Reliant, TXU, and Direct Energy run retail customer service for the deregulated Texas market. Routine queries dominate the call mix: outage status, billing inquiries, service start and stop. Surge handling for storm events is the operational priority. We design for a 50x baseline-to-peak ratio with autoscaling triggered by active-call count, pre-warmed from National Hurricane Center watch posts. Texas PUC reporting requirements wired into the call-outcome record.
Port of Houston drayage, container pickup at Bayport and Barbours Cut, customs brokerage. Call mix is mostly structured slot-filling: truck number, container ID, appointment window, gate code. Voice agent handles the routine 80 percent end-to-end with tool calls to the terminal operating system. Escalation to a dispatcher for exceptions, demurrage disputes, and rebooks. Bilingual flow important for owner-operator drivers.
Halliburton, Schlumberger, Baker Hughes, and the rest of the Energy Corridor majors run dispatcher lines for field-services calls and customer-account lines for commercial fuel cards and retail-fleet billing. Call mix shifts with WTI price moves and rig schedules. Voice agent handles routine account inquiries and dispatcher intake; escalation to a specialist for service-recovery and contract questions.
