Conceal your number, identity, and who you’re calling, no matter what device.
Holler places commercial SIP numbers between the caller and recipient to ensure user identities are hidden from recipients, snoopers, and even carriers, such as in call chains where calls are forwarded through SIP numbers between caller and recipient to ensure anonymity.
Holler's Calliope feature allows users to anonymously access a web-based portal from their browser where they can reserve numbers for misattributed calling from any device.
Using up to 5 SIP providers provides the maximum amount of global reach.
Integrate custom SIM cards to Holler for greater authenticity and flexibility.
Fognigma’s misattributable telephony Session Initiation Protocol (SIP) solution delivers a powerful, privacy-focused communications capability designed for businesses that need secure, untraceable, and compartmented phone operations.
Whether you’re conducting market research, running anonymous support lines (like an IT service desk), tip/anonymous reporting lines, or managing field teams, this system ensures your true corporate identity stays shielded while maintaining call quality and reliability. Holler is ideal for law firms, investigators, real estate professionals, and any organization that values confidentiality.
Fognigma’s telephony platform gives you flexible, rotatable numbers, secure routing, and complete separation from your core infrastructure, empowering you to communicate freely without exposing your business.
Fognigma’s ability to create invisible, self-owned, and encrypted digital networks makes it an ideal solution for enhancing HUMINT operations by ensuring secure communications, anonymized interactions, and operational security (OPSEC).
HUMINT operatives and assets often need to communicate securely without exposing their locations, identities, or affiliations. Traditional communication methods, even encrypted ones, can still leave digital traces. Holler can generate region-specific phone numbers that allow operatives to blend into local environments and communicate without linking back to U.S. intelligence agencies.
Military commands, government agencies, and deployed units rely on voice and SMS communications to coordinate with contractors, allied partners, logistics providers, and vendors in order to conduct the nation’s work. Doing so without exposing personnel identities, facility locations, or operational patterns is where Fognigma’s Holler telephony solution excels—operating entirely within invisible, self-owned Mission Partner Environments and routing every call and message through dynamically assigned, geographically diverse commercial numbers sourced from multiple Session Initiation Protocol (SIP) providers and multi-hop intermediary chains.
Recipients see only innocuous, context-appropriate caller IDs while the true originating device, installation, or IP address remains completely concealed. This prevents adversaries or third parties from correlating communications back to U.S. military, government, or mission partners, eliminates targeting of specific units or bases, and safeguards coordination during routine planning, acquisition, joint exercises, and training activities.
Accessible via desktop, VoIP, and mobile devices with full-featured extension dialing, voicemail, and seamless SMS bridging to collaboration tools like Mattermost, Holler delivers a compliant, ready-to-deploy telephony capability with no requirement for additional hardware or infrastructure changes.
Join thousands trusting Fognigma’s zero-trust networks for invisible, encrypted communication anywhere, anytime.
