BcsDIS – Directory Integration Server
BcsDIS is the SIP server application which, by means of directory integration mechanisms, allows clients access to external address books (personal address books, shared address books). These are made available to the client via BcsDIS which is a gateway able to transform the SIP requests of the client into requests in the communication protocol used by the external address books.
The most frequent case is that of external address books saved in Microsoft Exchange Server in Outlook contact folders made accessible via SOAP requests to the Exchange Server web service.
The current version of BcsDIS can connect with Exchange Server 2007 and 2010 and LDAP V3 servers.
