SMSEagle Voice Calls

The Voice Add-on is an optional module that enhances your SMSEagle with advanced voice calling capabilities. It enables you to deliver critical, emergency, or time-sensitive messages more effectively – ensuring your communication is heard, not missed.

What do you get?

1. Wake-Up Calls – attention-grabbing ring
A short ring signal (without playing any message) designed to instantly capture attention.
Perfect for night-time alarms, urgent technical alerts, or on-call staff notifications.

2. Text-To-Speech (TTS) – automatic message reading
Transform your text message into a voice call, delivered in the language of your choice.

Simple Mode – basic message reading in English only.
Advanced Mode – high-quality voice output, support for 36 languages, and the option to add your own voice models.
Ideal for companies, institutions, and emergency services that must communicate effectively in multiple languages.

Technical note: TTS is only available on NXS hardware Rev. 4 and MHD-8100-4G devices.

3. Audio File Calls – play a recorded message
Upload a pre-recorded WAV file and play it during a call.
Perfect for personalized announcements, voice alerts, or instructions for specific people or groups.

Why choose it?

Ensures the recipient immediately notices your message.
Works across multiple languages and formats.
Supports single or group calls directly from the SMSEagle web-GUI or via API.
Ideal for alarm notifications, public announcements, and urgent communications requiring instant attention.
