PVDM2-16 Use Case
High-Density VoIP Gateway with PVDM2-16 Channel Packet Voice/Fax DSP Module for Multi-Site Enterprises
An enterprise deploys Cisco ISR 4451 routers loaded with PVDM2-16 Channel Packet Voice/Fax DSP Modules at 20 branch offices to deliver up to 16 simultaneous VoIP calls per site. By offloading echo cancellation, voice activity detection and jitter buffering to the PVDM2-16 DSPs, the solution ensures carrier-grade voice quality and low latency. Outcome: maximized channel density, reduced hardware footprint and accelerated branch roll-outs with predictable OPEX.
Secure Fax-over-IP with PVDM2-16 Channel Packet Voice/Fax DSP Module in Regulated Industries
A healthcare organization implements Cisco ISR 4321 routers equipped with PVDM2-16 Channel Packet Voice/Fax DSP Modules to support T.38 fax over IP between multiple clinics. The DSP modules handle real-time fax detection, tone relay and error correction, ensuring HIPAA-compliant document exchange. Outcome: seamless legacy fax integration, elimination of costly PSTN lines and enhanced data security.
Seamless TDM-to-SIP Contact Center Migration with PVDM2-16 Channel Packet Voice/Fax DSP Module
A financial services firm migrates its on-premises contact center from a legacy TDM PBX to Cisco Unified Communications Manager by installing PVDM2-16 Channel Packet Voice/Fax DSP Modules in existing ISR 3945 routers. These DSPs provide voice transcoding, conferencing and echo cancellation for up to 16 concurrent calls, enabling a phased SIP trunk rollout without service disruption. Outcome: reduced telecom costs, improved call scalability and protection of existing hardware investments.
