Sometimes, my cell type cordless phones (KX-TD7680 or 7690) don’t ring
Assigning cordless phone extension number directly into an ICD group often causes this problem. The 7680 and 7690 cordless phones communicate with the phone system through cell station and therefore the communication path from the cordless phones to system is limited by the number of cell stations. The cordless phones ringing issue often appears when the number of cordless phones far exceeds the number of cell stations. The proper way to program cordless phones to ring is that first assign cordless phones into a PS ring group (groups --- PS ring group), then assign the PS ring group floating extension number into an ICD group and finally assign this ICD group number as CO line destination.
