IMPORTANT NOTE: Pansonic only supports 3 of the TD7895 or TD7896 on any one system at a time. This is due to the possibility of RF interference between handsets if large numbers of handsets are installed on one premises.
Note also that the TD7896 looks like a KX-T77xx series phone to the phone system and therefore can be supported on any station card that can support the KX-T77xx series deskphones.
