The Avaya IP500 VCM 64 Base Card provides voice compression channels for your Avaya IP500 system. Voice compression channels are required when using IP trunk or IP endpoint applications.
NOTE: Due to availability, we will substitute the IP500 VCM 64 V1
for the V2. The IP500 VCM 64 V1 provides the exact same hardware and functionality as the V2 and also includes 12 Avaya IP Endpoint activations when installed.
