A voicemail system comprising a user interface 108 that presents audio outputs to a user and receives inputs from the user, and a computer system comprising program code arranged to generate the audio outputs and to respond to the inputs from the user. The voicemail system also comprises a model generator 110 arranged to analyse the code and/or precursor code to the code to provide a representation of a graph representing various paths of execution through the code, e.g. a call flow diagram. The system also comprises a configuration tool to allow the operation of the voicemail system to be changed. The program code may be voiceXML.
