Über diesen Service
Is your corporate voice network dropping sessions, suffering from one-way audio, or exposed to SIP hacking? In enterprise voice environments, an unoptimized or poorly secured boundary edge leads to costly downtime, call failures, and critical security vulnerabilities.
As a Senior Voice Infrastructure Engineer, I specialize in deploying, configuring, and hardening enterprise-grade Session Border Controllers (SBCs) and network gateways.
Infrastructure & Hardware Platforms:
- Session Border Controllers: AudioCodes (Mediant/VE), Oracle SBC, Cisco, and Sonus/Ribbon.
- VoIP Gateways: Analog/Digital gateway integrations, FXS/FXO, and E1/T1 PRI lines.
What this Gig Covers:
- Comprehensive SBC deployment (Cloud, Virtual, or On-Premise appliances).
- Complete NAT traversal fixes, SIP normalization, and one-way audio resolution.
- Enterprise VoIP security hardening, topology hiding, and DDoS/Brute-force protection.
- Secure TLS/SRTP encryption setup for call signaling and media streams.
- SIP trunking peering, carrier interconnection, and advanced routing tables.
Note: Packages cover standard configurations. For high-availability clusters or multi-site setups, please message me before ordering!
