In multisite BSR applications, the 1st-found available agent strategy results in fewer interflows and minimizes the load on trunking. Communication Manager has less processing to perform for each call in BSR vectors as Communication Manager does not compare many resources to identify the best resource.

If the processing power and tie trunk capacity are issues in your multisite applications, use the 1st-found strategy.

The other strategies typically result in a much greater percentage of calls being interflowed, optimizing load balancing across locations.
