Abstract

A system, method, and apparatus for establishing a multiparty call isolating one or more parties (110) is presented. Input signals are received from each of the parties at an unrestricted party accumulator (215). The output of the unrestricted party accumulator is transmitted to each party (110b, 110c) except the restricted party(s) (110a). Input signals are received at a restricted party accumulator (220) from each party except the party(s) which the restricted party(s) is restricted from hearing. The output of the restricted party accumulator is received by the restricted party(s) (110a).
