AnyEdge SIP Load Balancer (Anycast)
High availability and surge protection for SIP infrastructure — delivered as a managed service.
Lower Latency, Globally
Anycast routing helps your users reach the nearest point of presence (PoP).
Surge & DDoS Protection
Up to 10 Gbps of L3/L4 protection, plus SIP-aware traffic controls.
High Throughput for Real Traffic
Designed for high CPS workloads with fast updates and failover.
Global Scale, Local Feel
Imagine giving your customers a single service IP that works worldwide.
With AnyEdge, you advertise the same SIP service IP from multiple locations around the world at the same time. When a SIP request arrives, the internet's routing system (BGP) typically delivers it to the nearest available edge location.
It's a safety net: if an edge location or path becomes unavailable, routing can shift to the next best location—without manual failover or DNS changes.
One Global IP
Connect to one service IP, worldwide.
Smart Routing
BGP selects the best available path based on routing policy and conditions.
Instant Failover
Traffic can shift quickly to help maintain service.
How AnyEdge Routes Traffic
Traffic is routed to the nearest available point of presence (PoP) via Anycast.
Automatic Failover
Seamlessly redirect traffic when issues are detected, helping maintain service availability.
Latency Optimization
Route users to the nearest PoP to help minimize latency and improve voice quality.
Real-time Load Balancing
Distribute traffic intelligently based on server capacity and health metrics.
Operational Continuity
Scenario: Server Failure
Even when a server goes down during peak traffic, AnyEdge is designed to help keep service online for your users.
In this simulation, notice how AnyEdge quickly detects the failing server and redirects traffic to the remaining healthy nodes. The system automatically rebalances the load, helping absorb the surge while minimizing dropped calls.
Instant Health Checks
Traffic rebalancing
Automatic Recovery
Elastic Scalability
Scenario: High Utilization
When traffic spikes and server loads climb, AnyEdge works with your orchestration layer to scale out quickly.
Watch as new capacity is provisioned in response to high utilization. AnyEdge automatically discovers the new healthy node and begins routing traffic to it, restoring the cluster to healthy performance levels.
Load Spike Detection
Dynamic Provisioning
Seamless Traffic Integration
Defense in Depth
Scenario: DDoS Attack Mitigation
Attacks can be mitigated at the edge. AnyEdge filters out malicious traffic before it hits your core infrastructure.
In this simulation, observe how the system identifies and blocks high-volume attack vectors (red lines) while legitimate SIP traffic (green lines) continues with minimal disruption.
Edge Scrubbing
Legitimate Traffic Priority
Infrastructure Protection
Zero-Downtime Ops
Scenario: Graceful Maintenance
Take servers offline without disrupting active sessions.
When a node is marked for maintenance, AnyEdge stops sending new calls to it and waits for existing sessions to complete. The server "drains" naturally until it is safe to remove.
Connection Draining
Safe Removal
Speed at the Edge
Scenario: Latency Optimization
Shorten the path your customers take.
Compare standard routing vs. Anycast. By entering the network at the closest local PoP, your users avoid the "zigzag" of the public internet, helping improve voice quality.
Standard: Long & Unpredictable
Anycast: Direct & Optimized
Built for throughput, failover, and visibility
Use real-time controls and metrics to keep calls flowing—even during spikes.
Contact salesCalls per second design target
Network-layer DDoS protection

Controls beyond L3/L4
Capabilities that map to real SIP problems
SIP-aware balancing, traffic controls, and observability—built for operations teams.
Compression
Reduce overhead where appropriate to keep signaling efficient during spikes.
Compaction
Optimize SIP message handling to improve throughput under load.
Validation
Apply SIP-aware checks to improve hygiene and reduce bad traffic impact.
CPS metrics and breach alerts
Monitor calls-per-second behaviour and spot overload patterns earlier.
Customizable NAT traversal

Registration proxy
Handle registration flows with policies that match your deployment needs.
Outbound proxy
Guide outbound traffic with more control over routing behaviour.
Distribution algorithms
Steer traffic across targets based on capacity, cost, and resilience strategies.
