Section 700 - Operation Chapter 3. System FeaturesS-ICX-50-700 S-ICX (International) issued October 2000 67Multiple RingingDescriptionMultiple Ringing allows trunk calls into the System to be directed to ring multiple extensions in theSystem. This can be very useful when anyone in a group may answer a call. This can also be veryuseful at night when only a selected number of people are available to handle calls.Hardware Requirements• N/AConsiderations• N/AVirtual PortDescriptionVirtual ports are not physical ports in the System. They are phantom or simulated ports used in theSystem to support:• Virtual extension ringing• Virtual floating holdUp to 96 virtual ports may be assigned to the CCU.Virtual Port used for Virtual ExtensionYou can assign an actual extension number to a virtual port. You can then assign the extension numberas any actual extension (incoming call settings and types, Station Class of Service (COS), tenantgroup, pickup group, etc.). You can also assign the virtual port to an FF key on one or more telephonesand set to ring. Any call directed to the virtual port extension number will ring the assignedtelephone(s).Virtual extensions provide a mechanism for ringing multiple phones simultaneously. For instance, aDirect Inward Dialling (DDI) entry can only be set to ring to one extension number. However, if theDDI is set to ring a virtual extension and the virtual extension is assigned to ring keys on multipleextensions, the DDI will ring the multiple extensions.Hardware Requirements• N/AConsiderations• N/AVirtual Port used for Floating HoldYou can assign a virtual port that is not assigned an extension number to be used for floating hold. Thevirtual port is assigned to an FF key. Calls can then be placed on hold on the virtual port FF key. Anyextension that is assigned the same virtual port FF key can then pick up the held call.This can be used like a system park feature.
