Apparatus and method for performing an equitable routing of calls within an automatic call distributor where calls are transferred to agent terminals from two sources, one controlled by switching equipment and the other controlled by a server. The server detects receipt of a call by a queue within the switching equipment and it determines whether other calls are waiting to be routed in the switching equipment. If other calls are waiting, the server withholds ready status of the agent terminals from the queue until the waiting calls are processed so that the switching equipment does not attempt to transfer calls from the source it controls, potentially conflicting with the waiting calls.
