EASG provides a secure method for Avaya services personnel to access the Avaya Aura® MS remotely and onsite. Access is under the control of the customer and can be enabled or disabled at any time. EASG must be enabled for Avaya Services to perform tasks necessary for the ongoing support, management and optimization of the solution.  EASG is also required to enable remote proactive support tools such as Avaya Expert Systems® and Avaya Healthcheck.
