A switching center for use in a communication network includes a pool of echo cancellation units for use in providing echo cancellation services to users associated with the switching center on an 'as needed' basis. A communication connection being supported by the switching center is analyzed to determine whether intolerable reflections are being received from an associated trunk. If such reflections are detected, one of the echo cancellation units in the pool is assigned to the communication connection for use in reducing or eliminating the reflections. When the communication connection terminates, the echo cancellation unit is returned to the pool for subsequent use with another communication connection.

An arrangement for lookahead interflowing traffic among a plurality of serving sites of one customer. Incoming calls received at a site are queued if they cannot be served immediately. Queued calls are then examined periodically and if the call has not yet been served by a local agent and if the call is one of the oldest call in the queue, then the call is a candidate for lookahead interflow. A candidate for lookahead interflow causes a message to be sent to another switch requesting that the call be interflowed. If the other switch accepts the call, the call is routed to that other switch; if the other switch does not accept the interflowed call then the call remains in the queue of the requesting switch and is reexamined at the next period. All calls in the queue are completed to a local agent if a local agent is available.
