Gatekeepr ENUM

Gatekeepr is a purpose-built ENUM platform for Azure that gives organizations full control over their voice routing. It translates E.164 telephone numbers into SIP URIs through DNS-based ENUM lookups (RFC 6116), enabling efficient, standards-based number resolution at scale.

Designed for telecom carriers, VoIP providers, and enterprise voice environments, Gatekeepr eliminates the complexity of building and maintaining ENUM infrastructure. Each deployment includes a high-performance DNS engine, web management portal, PostgreSQL database, and built-in load balancer — all provisioned automatically through the Azure Portal.

Gatekeepr is available in multiple editions to match your scale and availability requirements, from single-node deployments to fully redundant, multi-node architectures.

Key capabilities

• High-performance ENUM DNS engine — Sub-5ms average query response time with PowerDNS at its core, purpose-built for carrier-grade number resolution.

• Web management portal — Intuitive browser-based interface for managing ENUM records, zones, and system configuration. Secured with HTTPS and automated SSL/TLS certificates.

• Unlimited ENUM records and queries — No artificial limits on the number of records or DNS queries. Scale your number ranges as your business grows.

• Bulk operations — Import and export ENUM records via CSV for efficient bulk provisioning and migration.

• Real-time analytics dashboard — Monitor query volumes, response times, and system health through a built-in analytics interface.

• Enterprise security — Network isolation with Azure Virtual Network (VNet) and Network Security Groups (NSG). GDPR-ready architecture with data residency within your Azure region.

• DNS load balancer — Built-in load balancer on port 53 for consistent query distribution.

Session Border Controller compatibility

Ideal for

• VoIP providers and telecom carriers looking to deploy or modernize their ENUM infrastructure on Azure.

• Enterprise voice environments seeking centralized number routing with SBC integration.

• Service providers evaluating ENUM who need a low-risk, rapid deployment to test ENUM-based routing.

• Organizations modernizing voice routing and transitioning from legacy number translation systems.

Deployment

Gatekeepr is fully automated through the Azure Portal deployment wizard. No manual server configuration required — the VM, networking, DNS engine, database, and web portal are provisioned and configured automatically. Typical deployment completes in under 15 minutes.
