`ABSTRACT
`
`A method and system of providing telephone service com(cid:173)
`prises associating a list of telephone numbers with a repre(cid:173)
`sentative telephone number. A call to the representative
`telephone number is detected and a plurality of telephone
`numbers on the list are simultaneously signalled. Thereafter,
`signalling is terminated at at least one of the plurality of
`telephone numbers thereby allowing a connection to be
`established with one or more parties at telephone numbers
`among the plurality of telephone numbers. Each telephone
`number on the list may be a representative number which is
`associated with another list of telephone numbers.

`at any time.
`In another embodiment of the present invention, at least

`number with its own list of associated telephone numbers. In
