Abstract
A facility is disposed in a telecommunications network which, advantageously, establishes a conference (N-way) call more efficiently than was done priorly. Specifically, a caller may establish a N-way call by dialing a code representing a sequence of speed dial codes respectively associated with the telephone numbers of the conferees that will be involved in the N-way call, rather than dialing each such telephone number. The facility, responsive to receipt of the dialed code, identifies the associated sequence of speed dial codes and places a call to each of the telephone numbers associated with those codes. In this sense, one code represents a plurality of telephone numbers.
