From the developer:
GigaSync is the missing link between your Siemens Gigaset DECT handsets and your Mac.
It allows you to synchonize any contact group of your Mac address book with any of your handsets.
Synchronize one contact group to all your handsets or use a separate group for each handset.
GigaSync works with any Gigaset handset that's compatible with QuickSync.
