	att_abstract={{Mid-call telecommunication features act only after an initial media connection has been set up.  Many mid-call features perform complex functions such as handling multiple far parties and multiple devices.  They cause many important feature interactions that are little known and poorly understood.  Using the example of personal features associated with a mobile phone, this paper presents a general method for analyzing the interactions of mid-call features with each other and with other features in a service.  The paper discusses how to determine the most desirable behavior of interacting features.  It also shows, as a proof of existence, how to manage these interactions in pipes-and-filter implementations of telecommunication services.}},
