VoiceLayer is a developer platform that enables developers of field service applications—e.g., for construction, hospitality, fleet management—to efficiently integrate enterprise-grade Push-to-Talk (PTT) communications into any mobile or desktop app. \n\nVoiceLayer delivers a broad suite of supporting enterprise features, such as IP-Radio gateways connecting smartphone and walkie-talkie users, on-premise servers, and advanced audio management.\n\nVoiceLayer was built on Ericson’s Erlang for superior reliability. It employs Google’s QUIC transport protocol for very low latency PTT under poor network conditions. \n\nOur second product, MODULO, is a standalone PTT walkie-talkie app built atop VoiceLayer. MODULO is FirstNet Certified by the US government for mission-critical use by first responders.
