I agree with Ted's concerns. In particular, "premature call  
termination" has never been defined precisely and many of the fears  
are based on the old single-line physical phone model which just don't  
apply here. Carrying forward notions that apply to black phones with  
rotary dials just seems unhelpful. In particular, the topic is  
strongly connected to call-back and should not be treated in isolation.
