DSP Modules for Enhanced Voice Processing and Call Quality

Deploy DSP modules to boost VoIP performance, enable conferencing, transcoding, and improve call processing on enterprise-grade routers and gateways.

What is a DSP Module?

A Digital Signal Processor (DSP) module is a specialized hardware component used in voice-enabled routers and voice gateways to handle real-time audio encoding, decoding, and transcoding. It offloads processing tasks from the router’s main CPU, ensuring reliable and high-quality voice communications.

Use Cases of DSP Modules

VoIP call setup and teardown
Echo cancellation and noise suppression
Codec conversion (e.g., G.711 to G.729)
Conferencing and media termination

Why Are DSP Modules Important?

In unified communications and hybrid voice environments, DSP modules ensure call reliability, reduce jitter, and optimize CPU load for scalable deployments. They are critical in call centers, enterprise PBXs, and SIP trunking setups.

Compatible Devices

DSP modules are typically used with Cisco ISR routers (e.g., 4000 series) and digital voice gateways. They are available in various capacities to support different numbers of simultaneous calls and conference sessions.
