A conference bridge is selected for a conference call so as to reduce the overall cost of the conference call, and the conference bride selected may be changed dynamically, e.g., as parties are added or dropped from the conference call, so as to continuously maintain the low cost of the conference call. User telephones are connected via device servers, which may include a packet circuit gateway (PCG), to a packet network which provides both transport and service. Accordingly, in response to a request for a conference call, the packet network determines the parties to be on the conference call and selects a conference bridge that results in the lowest cost for the conference call, e.g., a bridge located more closely to two of the parties on the conference call. In the event the parties on the conference call change, e.g., by adding an additional party and possibly also by dropping a party already on the call, a new conference bridge is selected for the call that would keep the cost low for the call as configured with the revised parties and the information streams from all of the parties that remain on the call are directed the new conference bridge. Once the transition to the new conference bridge is completed, the old conference bridge is released for use by another conference.
