Some phone numbers belong to positions, others belong to people and yet others belong to 
the whole institution. You should  differentiate them.

Think about it as:

Institution:  Inst Name, Address, Switchboard Phone #
     Position - Posn Name, Bus Phone # etc
         Person - , Pers Name, Pers Phone #, email etc

Institution/Person is one-to-many
Position/Person is potentially many-to-many
