Calls

Turn a critical alert into a phone call, automatically

A text alone does not always wake someone up. SMSEagle can escalate any alert to an actual phone call, so it can’t be missed.

Calls: Turn a critical alert into a phone call, automatically

Wake-Up Call lets an urgent alert ring the phone directly, even at 3am

For alerts that truly cannot wait, a text sitting unread on a phone does not help anyone. A Wake-Up Call rings the phone directly, urgent enough to get someone’s attention even when they are asleep.

With Text-to-Speech, a written message becomes a spoken call automatically

Manually recording or reading out the same announcement for every alert wastes time. Text-to-Speech automatically converts your written message into a spoken call, no recording required.

An important call never has to sound robotic - Voice Calls with ElevenLabs use natural, lifelike speech

A message that sounds obviously automated can be easy to tune out. Voice Calls with ElevenLabs generate natural, lifelike speech, so important calls sound like they matter.

Choose the right kind of call

Wake-up calls for pure attention, Text-to-Speech for spoken messages, or Audio File calls for a pre-recorded announcement, pick whichever fits the alert.

Speech in many languages

The Advanced TTS voice model library covers a wide range of languages, with multiple voices for some of them, plus lifelike ElevenLabs-generated speech when you need it.

Trigger a call from web-GUI or API

Start any call type manually from the web-GUI, or automatically as part of a rule, workflow, or API integration.
