Presence Synchronization Interface (PSI)

The Presence Synchronization Interface (PSI) enables that presence information shown in Sinch Contact Pro follows the user availability information of a third party system, such as Microsoft Lync. The interface is based on the SOAP version 1.1, and uses HTTP protocol to carry messages between a SOAP client and itself. For authentication and authorization issues, see Common Integration Interface Features.

Using PSI requires that the interface is enabled in Sinch Contact Pro, the corresponding counterpart is installed on the third party system, and that a Presence Synchronization Token is configured for those user groups that use it (see User and Role Management > Managing User Groups in System Configurator ) and the third party user id is configured for those users as well (see User and Role Management > Creating New User Accounts > Entering Authentication Information in System Configurator).
