Actually, the "RJ" numbers are wiring patterns for specific
applications, not the connectors. They are named *p*c, for the number
of postions and the number of conductors.



A somewhat narrower version is used for handset cords for phones
of a certain age.

That is the 4P4C wired as a four conductor handset cord. The one in
picture 796 is the 4P4C, as used for handsets.
