AVAYA 700417397

This card provides voice compression channels for use with VoIP calls, SIP trunks and IP-based voice networking. The module is available in variants of 32 or 64 channels. The actual number of channels enabled is controlled by a VCM Channel license entered into the IP Office 500 system configuration.

Each VCM card has 4 VCM channels enabled by default. Further channels can be enabled up to the maximum (32 or 64) through adding one or more licenses (available in 4, 8, 16, 28 and 60 channel increments).
