For which requirement should AAMS-CM be deployed instead of a MG?

Although the Avaya Aura® Media Server adoption of Communications Manager (AAMS-CM) provides many of the resource capabilities of the G-series Media Gateways (Mg), it is not a direct replacement. therefore, with Avaya Aura® and Communications Manager (CM) 8.0, both AAMS-CM and MGs are sold as media resource options. AAMS-CM can support more channels per instance than a g series a gateway.
