Re: [Sipping-tispan] Requirements -02g

["ZhouQing(Justin)" <[e-mail]>]

Hi Miguel,

I have a holiday last week and sorry for the delay.

Thanks for your detail, it is clear and reasonable, it makes me 
agree with you that the callee and the network intermediaries
may not have the requirements obviously to be aware that "something 
is going on right here right now". 

As we seem, it has requirement for the network intermediaries to be 
aware that "something went on" (-3 and -4), so I think that the network 
intermediaries have the requirements to be aware that the communication 
was diverted or not, so that the network intermediaries(eg. voice mail 
server) can provide personalized services according to the communication
diverted information.

Do you think we have the requirements for the callee and the network
intermediaries to be aware that the communication was diverted? 
Thank you. 

Justin
