Description: The Unify OpenScape Desktop Client is an Internet Protocol (IP)-based communications software that can be used as a Session Initiation Protocol (SIP) or Hot Fix Accumulator (HFA) softphone when connected to a (SIP) or a (HFA) communications system. It is installed on a computer and enables mobile users to take their phone number with them. Calls can thus be made and accepted independently from the location. In addition, it enables managing a local contact list, integrating corporate directories and private contact lists (for example Microsoft Outlook contacts) via Lightweight Data Access Protocol (LDAP) as well as calling Microsoft Outlook contacts directly from Microsoft Outlook. During operation, all calls are logged in a local journal. In combination with an OpenScape Voice there is the option of conducting video phone calls and taking part in video conferences with up to three participants.

This entry covers the Desktop Edition of this technology and not any mobile versions. See Category tab/Comparable for the corresponding Mobile entry.
