One of the requirements of a proposal you are working on, is the ability to query an Active Directory database for contact Information from the customer's Avaya 96XX SIP Phones.
To support this functionality, which component must be included in your solution?

In preparation for the migration of CS1000 phones to Avaya Aura, your customer is trying to understand how things will work after the migration.
How will CS1000 phones register?

You are explaining to your customer that Avaya Aura Media Server (AAMS) has been adopted by Communication Manager, but Is not a direct replacement for media gateways.
Which two capabilities are supported by the Avaya Aura Media Server? (Choose two.)

A customer has an existing single-location Communication Manager solution with G650 gateways and ISDN trunks. You have been asked to design a new location for 200 users. The new location will support IP telephones, basic emergency calling to public safety agencies, and local PSTN trunks. There is a requirement for Standard Local Survivability.
Which design meets the customer's requirements?

You are designing a Communication Manager (CM) 8 solution with centralized ISDN trunks at the main site and two remote gateway locations. Each remote location will be connected to the main server via dedicated, point-to-point WAN service. Main - CM 8.1 duplex pair with 2-G450s and 250 IP stations Remote 1 - S8300E LSP/G450 with 125 IP stations Remote 2 - S8300E LSP/G430 with 30 IP stations.
To ensure that no one site Is overwhelmed by CM traffic, what is the recommended number of network regions required for this design?
