Yes, sure... I think this is an obvious requirement for each service, 
isn't it. Do you think we need to state it explicitly?

Is this a true behaviour of the service? If someone invokes CCBS on me, 
he will block automatically all my other calls to me? This sounds like a 
  policy that certain network might have, but sounds a bit weird to 
write this as a requirement. Can anyone else comment?

Good idea. So far I have been trying to draft the requirements in 
sequential order. I thought this would be easier to understand. Can you 
indicate what would be the suggestion for better understand? I mean, 
which groups will you form and which requirements will you group?
