Technical FAQ

Frequently Asked Questions

Clear answers on webhooks, remote SMS, and API endpoints.

How does inbound remote SMS dispatching work? ▼
Your Android device maintains an encrypted, battery-efficient WebSocket connection to our Cloud Relay. When your cloud pipeline (e.g. n8n or Make) performs an HTTP POST to https://api.missedcallautosms.com/v1/send-sms with your API token, the Cloud Relay routes the payload to your phone, which transmits the SMS locally through its native carrier SIM card in <500ms.
What events trigger outbound webhooks? ▼
The Pro Gateway fires real-time webhooks on: mcasms.missed_call (inbound missed call), mcasms.auto_sms_sent (local auto-reply dispatched), mcasms.sms_received (incoming customer SMS reply), mcasms.voice_call_completed (AI voice call finished with transcript and sentiment), and mcasms.telemetry_ping (battery and signal status).
Can I mute native auto-replies to let my CRM handle logic? ▼
Yes! In the app settings, you can enable "Mute Native SMS". The phone will still detect all missed calls and fire the webhook to your CRM/n8n, but will not send the default auto-reply, allowing your custom workflow to evaluate lead tags and respond conditionally.
Can I upgrade from Founder's Base to Pro later? ▼
Yes! If you already own the $49.99 Founder's Base license, you can unlock the Pro Automation Gateway directly inside the app for a prorated $249.99 upgrade fee with zero loss of data or configuration.
How does the device handle sleep / Doze mode? ▼
Missed Call Auto SMS runs as an Android Foreground Telephony Service with high-priority battery optimization whitelisting. Even when the screen is off or the phone is in deep Doze mode, inbound telephony events are captured instantly by the native Android OS broadcast receiver.
