PSTN User Authentication
Microsoft Unified Communications Managed API (UCMA) 3.0 applications add the ability to authenticate a user to the Microsoft Lync Server 2010/Microsoft Exchange Server 2010 servers by means of a Lync Server 2010 user personal identification number (PIN), or by authenticating a user separately, and then using server trust to take actions on behalf of that user.
UCMA 3.0 includes the class, which has a method that can be used to verify a PIN.
With the ability to authenticate users by PINs, a mobile user can call a UCMA 3.0 applications, present a single PIN, and then be authenticated to his or her Exchange Server 2010 mailbox to perform such tasks as reading mail using Text-To-Speech (TTS) or accessing his or her contact list. The Voice Companion sample that ships with Microsoft Unified Communications Managed API (UCMA) 3.0 Core SDK demonstrates how these actions can be carried out.
