Abstract
A system for routing telephone calls from a calling party instrument to a called party instrument and involving at least one internet protocol network includes: (a) a first internet protocol interface apparatus effecting a first communicative coupling between the calling party instrument and the at least one internet protocol network; (b) a second internet protocol interface apparatus effecting routing telephone calls according to routing criteria to establish a second communicative coupling between the at least one internet protocol network and the called party instrument; and (c) a call routing system apparatus coupled with the second internet protocol interface apparatus and storing information relating to a geographical or geospatial relationship of calling party instruments and called party instruments. The second internet protocol interface apparatus and the call routing system apparatus cooperate to establish the routing criteria.
