Abstract: An echo canceller pool configuration is provided that allows a user to predetermine and individualize the echo cancellation parameter settings for any echo canceller in the pool, based on prior knowledge of the echo path characteristics of the specific transmission route to be used for an ensuing call. The echo canceller with the individualized parameter settings is then switched into that route for the duration of the call. For example, at call setup, once a trunk route has been identified that will be used to complete the call, a "flag" is retrieved that is associated with that specific route. That "flag" identifies specific echo canceller parameter settings to be used for that route. Those parameter settings are downloaded to the echo canceller device selected from the pool, and that device is then switched into the specific trunk involved. An operator can thereby optimize echo cancellation in the system and significantly improve speech quality overall.
