Abstract: A method for managing callers into a conference system having a specific conferee limit for servers has steps as follow: for a first caller over the limit for a first conference server, the first caller electing a first conference, establishing a first tie line to a second conference server, and placing the first caller in a continuation of the first conference in the second conference server, for a subsequent caller over the limit, electing to join the first conference, placing the subsequent caller in the continuation in the second conference server, and for a subsequent caller electing to join a conference other than the first conference, determining that there is a listener in the first conference, moving the listener to the continuation in the second conference server, and accommodating the subsequent caller in the first conference server in the conference elected, preserving the single tie line.
