in this case the msc 2 5 would first determine if the call was destine for an emergency call center or another similar address if the call was so destined the services node 2 4 would not be involved in the call routing in the services node 2 4 architecture the incoming communications request 2 2 from the communications device 2 1 would arrive at the msc 2 5 and be routed to the services node 2 4 the services node 2 4 would then apply the logic to determine if the call setup should be delayed an urgent or other similarly marked message should be played and input collected before call setup progressed if the call was destined to be routed while the message was being played to the user of communications device 2 1 the services node 2 4 would route the communications request over the communications path 2 9 to the msc 2 5 using the identity of the communications device 2 1 and normal call setup would proceed the call routed over the communications path 2 9 would be marked to indicate that the services node 2 4 had already processed the call thus eliminating the.
