IP phones with card reader

Card reader

— a device for working with removable memory cards. In some phones with card readers, such media supplement the built-in storage, in others they are the only available storage. The functionality of the card reader may be different, depending on the capabilities of the device itself (storage of recorded calls, contacts, messages, firmware updates, etc.). Anyway, this feature provides additional options for storing various data, and also facilitates the exchange of data with other equipment (for example, smartphones or tablets).
