ContactsPush is a free Android application designed to facilitate the seamless transfer of contacts from your smartphone to Gigaset DECT handsets. This app is particularly useful for users of various Gigaset fixed line phones, including the A510 IP, C430(A) IP, and many others. With a user-friendly interface, it allows you to connect your smartphone to a local network and easily select which contacts to transfer to your phone system. You can choose to transfer all numbers for a contact or just one per type, streamlining the process according to your needs.

The app also includes a filtering feature to help locate specific contacts quickly, and offers the option to delete all existing entries on your fixed line phone before initiating the transfer. The operation is straightforward, requiring only an internet-capable Gigaset phone and a connection to the local network. For those without internet access, manual entry of the phone's IP address is also supported, ensuring flexibility and convenience.
