Abstract

A method for assigning access information for a teleconference to a group of conferees comprises assigning a conference I.D. number to the group of conferees, and dividing the conference I.D. number into a first portion and a second portion. An input sequence is derived from the first portion of the conference I.D. number and assigned to the group of conferees. A PIN is derived from the second portion of the conference I.D. number and assigned to each conferee of the group of conferees. In another embodiment, a teleconferencing bridge includes a programmable device effecting a sequence of instructions comprising receiving information derived from a first string of digits entered by a conferee, receiving a PIN entered by the conferee, deriving, from the PIN and a portion of the information derived from the first string of digits, a conference I.D. number, and validating the conference I.D. number.
