Communications-capable devices and agents can each register with a single address of record (AOR), or other such identifier. Various AORs or virtual AORs (VAORs) can then be mapped together whereby a device can be associated with multiple groupings, such as for households where devices may be shared amongst two or more users. The ability to maintain mappings between the AORs/VAORs enables the devices to be associated with multiple groupings while only registering with a single AOR, and simplifies the call routing logic as call connection requests only need to specify a single AOR/VAOR to reach a particular user or grouping of users via the corresponding registered devices.
