Proxy Server
Carrier-grade proxy server for SIP routing and load balancing.
Redefining Proxy Server
Protect and optimize your voice infrastructure with the MoosePBX Carrier-Grade Proxy Server. Sitting at the edge of your network, our proxy acts as a secure, high-speed traffic director. It inspects inbound SIP packets, shields your core PBX from attacks, and intelligently load-balances traffic across multiple backend servers to ensure 100% uptime even during massive traffic spikes.

Frequently Asked Questions
Everything you need to know about this service.
Does the proxy handle media (audio)?
No, our SIP proxy strictly handles signaling. Media (RTP) is either routed directly between endpoints or through a dedicated media relay (like RTPengine) to ensure maximum proxy performance.
Can it block toll fraud?
Yes, we implement strict rate-limiting, geo-blocking, and anomalous behavior detection to stop toll fraud in its tracks.
