Enterprise VOIP Server
Enterprise-grade private VOIP infrastructure using Asterisk PBX for high-concurrency internal communications.
Scalable Voice Architecture
The client required a unified communication system completely decoupled from public cloud vendors. We designed a massive, bare-metal Asterisk implementation capable of bridging SIP trunks across globally distributed offices.
High Concurrency
Maintains stability over 10,000 parallel active calls.
End-to-End Encryption
SRTP and TLS implementation for preventing packet sniffing.
Dynamic Routing
Intelligent IVR and load-balancing across SIP nodes.
Technical Strategy
Scaling an open-source PBX to enterprise levels required severe kernel-level optimizations and network topology planning.
Kernel Bypass
Implemented DPDK (Data Plane Development Kit) to drastically bypass the Linux kernel networking stack for VoIP packets.
Database Replication
Real-time MariaDB replication for CDR (Call Detail Records) preventing database locks during high volume traffic.
Failover Systems
Automated IP-takeover using KeepAlived allowing seamless fallback to redundant hardware in under 500ms.
