Klappentext

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. OfficeSIP Messenger is freeware SIP compliant instant messaging client developed by OfficeSIP Communications since 2008. Features include instant messaging, Voice Over IP, and Video Conferencing. OfficeSIP Messenger uses a number of Microsoft's extensions to the SIP protocol for Enhanced Presence features. As is the case with most SIP proxy servers, that have not implemented these publicly available extensions may not work correctly.
