Plantronics Discovery 975 supports multipoint
technology, which allows you to use one earpiece

multipoint feature on. When this feature is off, your
earpiece can connect to only one Bluetooth phone.

that most recently made an outgoing call. To use the
second phone, initiate the call using the controls on
the second phone.
