The Avaya IP Office 500 V2A (IP500 V2A) Control Unit is the core system processor and hardware foundation for the Avaya IP Office unified communications architecture. Designed to meet the evolving telecom demands of growing enterprises, the V2A hardware iteration provides improved power supply architecture and hardware components over previous control unit generations while maintaining full backward compatibility with IP500 expansion modules and software features.
Featuring four primary expansion slots on the front panel, the IP500 V2A accommodates a wide selection of base cards—including Combination Cards, Digital Station Cards, Analog Phone Cards, VCM (Voice Compression Modules), and Trunk Daughter Cards (PRIs, BRI, Analog Trunk). The system incorporates two System SD card slots (System and Optional) for operating firmware, voicemail storage, and license activation. Operating as a hybrid system, it supports up to 384 endpoints (IP, Digital, and Analog) and up to 8 external expansion modules, providing an adaptable path for enterprise VoIP transition, remote worker connectivity, and multi-site networking.
