Read those two and you should have a pretty good idea of what  
partitions and calling search spaces do.

Hi Guys;



I am getting ready to take the CCIE Voice Written exam; I have been  
studying and reading for a while and I have a question. This question  
on a simulator has me kind of stumped. It goes like this.



Considering  Phones A and B. Both are registered in the same cluster.  
Phone A is configured with Extension 1000 and Phone B with Extension  
2000.  Indicate Below what choice below is necessary and sufficient  
to allow Phone A to Call to Phone B AND Phone B call Phone A



a)      Both (a) and (b)

b)      Both Phones are assigned the same CSS

c)       Both phones are in the same partition

d)      None of the above



The sim says the answer is D, None of the above.



It is my understanding that two phone in the same partition should be  
able to call each other.



My question I guess is, Is the Sim simply wrong? I suspect it has  
something to do with the words Necessary and Sufficient but I can’t  
quite place it. I want to figure it out as I don’t want to just take  
it on faith.



Any pointers would be greatly appreciated





Jorge
