One Call Now vs. SIGNL4

One Call Now is one of OnSolve’s market-leading mass notification systems that enables groups and organizations of all sizes and types to send important messages via voice, text, mobile app and email to groups—all through a simple click or call. When you need to get the word out quickly—regarding severe weather, utility outages, school closures and more—One Call Now makes it easy to create and send alerts from anywhere.

SIGNL4 is an operational alerting and response platform that ensures critical events, alerts and incidents trigger immediate action - anywhere. Modern monitoring, IT infrastructure, cloud services, and IoT systems can detect problems instantly - but problem detection alone does not guarantee response. Simple notifications sent via email, SMS, or chat are often missed, delayed, or fail to reach the right person, especially outside the office or during off-hours. SIGNL4 ensures that critical alerts reach the right responders - wherever they are and in a fully automated manner.
