RtpBridge technology

RtpBridge is a proprietary GarantPlus development that bridges the packet VoIP world (RTP) and the circuit-switched TDM world (E1) at the hardware level. Voice processing is handled by DSP resources rather than the CPU, so quality and latency stay predictable even under load.

Performance

• Up to 30 simultaneous SIP ↔ E1 connections per stream
• Up to 30 E1 ↔ E1 connections (transit, cross-connect) per stream
• Hardware echo canceller on every channel
• SIP and PRI signaling is handled by the embedded Asterisk

Why it matters

This approach offloads the CPU, delivers clean audio at the TDM/IP boundary and enables reliable solutions — from connecting a single PBX to operator transit nodes.
