endpoint 101 1 presents to its user the status of the waveform transmission via the user interface i e display 205 loudspeaker 206 and or vibration mechanism 207 of endpoint 101 1 the status is based on the quality indication whose value was adjusted at task 305 the method of presentation to endpoint 101 1 39 s user e g visual audible tactile etc in some embodiments depends on the value of the quality indication as adjusted at task 305 furthermore in some other embodiments the method of presentation to the user depends on the audio mode in which the user operates endpoint 101 1 e g with a handset with a headset with a speaker etc for example if the user operates endpoint 101 1 using an audio mode in which the endpoint is held close to the ear it might be more effective to provide a tactile sensation to the user for the purpose of providing the quality status as those who are skilled in the art will appreciate the presentation method can be based on a combination of the quality indication value the audio mode and other characteristics of endpoint 101 1 the user the call and or the information exchanged between endpoints if the presentation method is visual display 205 can render the value of the quality indication in one or more of a variety of formats such as by using different numbers different colors different numbers of bars smiley face frowning face icons and so forth at task 308 endpoint 101 2 presents to its user the status of the waveform transmission via the user.
