Abstract
A telephone caller is permitted to retrieve his call from the central voice services feature of an unavailable called party, and resume the call progress by substituting a calling feature of his own. In a telephone system including a telephone switching facility and a voice features server, provision is made for enabling a calling party to invoke an appropriate calling party feature such as a ring back feature or an override feature, and thereby subsequently achieve a real time conversation with the called party instead of simply being able to leave a voice message for the called party.
