Key Takeaways
- Scenario 1646 is echo 08:50 attend DLR — not morning visit, imaging, pharmacy, vax, fasting, INR, infusion, TTO, dialysis, MH DNA, antenatal, dilate-wait, audiology, phlebotomy, derm biopsy, physio DNA, SLT, chiropody, orthotics, plaster, endoscopy prep, sleep-kit, MRI contrast, chemo pre-med, OH needle-stick, colposcopy 09:40, or cardiac-stress 07:15.
- An “arrive by 08:50, bare chest” SMS without delivered is a wasted sonographer slot.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 300 SMS lifetime, 1 device. Developer is 25,000 SMS per year.
- Starter is 2 devices; the clinic spare still counts.
- Hold fundraising CSV until echo DLR drains.
- Canary the echo SIM at 08:30, not at last night’s EPR health check.
Summary
Scenario 1646 is echo attend at 08:50: reminder out, failed DLR retried, charity CSV held until receipts drain. Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance.
If the sonographer thinks they are coming and DLR is still pending, you did not remind. You reserved an empty couch.
Not a CodeCanyon “clinic SMS” pack. Device meters apply — Twilio vs Android SMS gateway.

Context
First slot is 08:50. Patients need a delivered ping, not a queued one. Fundraising still wants a raffle CSV.
Free (300 SMS lifetime) is a rehearsal clinic. Developer is 25,000 SMS per year.
Core scenario guidance
08:50 is echo attend, not cardiac-stress 07:15. Timezone is the echo suite, not the trust HQ.
Echo DLR roles
| Role | When | Typical fail |
|---|---|---|
| 08:50 attend SMS | 08:50 patient local | Phone in a locked echo room after 18:00 yesterday |
| Failed DLR retry | Own template, 12 min later | Merged into the 08:50 body |
| Staff OTP | Transactional, own pool | Dumped onto the echo radio |
| Raffle / charity | Held until last attend DLR | Released at 08:20 into clinic SMS |
Cost and ownership
Priced by devices and SMS send volume. You use your own phone and operator SMS credit. The clinic spare is a billed device. Duplicate attend SMS burns airtime.
Name an 08:10–11:00 on-call for echo lists, not only weekday admin.
Operations
08:30 canary. Abort: hold raffle, keep staff OTP, skip a second “all patients” blast. Do not “resend echo.”
Security and compliance
Short bodies. No diagnosis plus DOB in one SMS. Authenticate EPR hooks. Raffle lists are promotional.
Decision guide
Ship when 08:30 canary is green and DLR retries stay on the echo radio. Delay if phones lock after 18:00. If handsets are forbidden, CPaaS for staff OTP.
Checklist
- Echo SIM paired overnight.
- 08:30 canary.
- Spare live before 08:50.
- Staff OTP isolated.
- Raffle held.
- Airtime before 08:10.
- Battery exemptions.
- Suite locale.
- Echo-list on-call named.
- Device cap includes spare.
Next steps
Review device and SMS volume pricing, device setup, SMS API documentation.
Deep dive: production hardening
Estates killing USB at 08:05 is an outage at 08:50. Watch DLR, not EPR 200s.
Deep dive: scaling and failure modes
Multi-site echo weeks add devices before inventing a hidden unlimited-handset SKU. Raise OEM ceilings; fair-use remains.
Deep dive: integration discipline
Idempotency on appt_id + kind (attend|retry). MCP is a REST wrapper — live fields in Developer Center.
Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
08:30 echo drill
Canary. Fire one attend SMS. Confirm DLR before raffle CSV. Hold charity during the wave.
