Groupware ConnectionParent topic: Managing Sametime Unified Telephony components
You use the groupware connection to connect the Lotus Sametime Unified Telephony system to an external groupware system. Lotus Sametime Unified Telephony users are hence enabled to access their respective groupware data under Telephony Application Server.
Via the LDAP connection you connect Telephony Application Server to one external LDAP directory at the most. In this way you can provide an LDAP-based global contact list to Lotus Sametime Unified Telephony users.
