The authentication may be communicated to Authentication Logic 320 by setting of a flag, providing an access key, providing query access to Client Data Storage 310, returning a variable indicating success, and/or the like. In some embodiments, once Access Device 110A is authenticated for a particular communication session it is assigned a session identifier (ID). The session ID includes a value that may be used to automatically re-authenticate Access Device 110A if the connection between Access Device 110A and a first service agent on CRM System 120A is transferred to a second (or additional) service agent on CRM System 120A. The session ID is optionally provided to Authentication Agent 235 for this purpose. Typically, once the communication session is concluded privileges of the session ID are cancelled such that it cannot be reused to authenticate any of Access Devices 110.
