The problem is, if lines 1,3,4,5,6,7,8,9,10,11 and 12 are plugged in, 

you would only be able to make 1 concurrent call...(because the next 
call would try to go out line two which would never work)...maybe if 
four people called at the same time only 1 wouldn't get through but 
then the next call wouldn't get through...

Is this so?
