AT&T Voice DNA^℠ Service provides a network-hosted, Session Initiation Protocol (SIP)*-based communications solution via the AT&T Global Multi-Protocol Label Switched (MPLS) Network.

 An essential component of AT&T Voice DNA^℠ Service is the availability of a web-based tool for company administrators to use to provision end users with AT&T Voice DNA^℠ Service, grant access to appropriate individuals, and maintain the service features. This is the AT&T Voice DNA^℠ Administrator Application on AT&T BusinessDirect.

 * Note: SIP is an application layer protocol that uses text format messages to set up, manage, and terminate multimedia communication sessions.
