Handsets that are capable of contact synchronization via Bluetooth or USB process contact data using VCARD (.vcf) format. Version 2.1 is used supported as listed below. When using a Gigaset IP base, the phonebook of a handset can be saved via the web interface of the base and also be saved back to the handset (Settings --> Directories --> Directory Transfer). It is also possible to send and receive VCARDs via Bluetooth as long as the handset is equipped with Bluetooth.
Please note that later VCARD versions may contain a different field name which cannot be recognized by our devices. If you use an external software to create/alter VCARDs, please keep this in mind.
