Abstract
In a telecommunication system having at least two communicants (i.e., a caller and a callee), a system and method are presented for collecting information associated with the geographical location of either of the communicants. In one embodiment, the approach entails receiving a geographical location corresponding to a public switched telephone network (PSTN) telephone number, and collecting geographical location information associated with the received geographical location.
