Situation where there are a lot of AgentErrorCount in Call Type
Abandoned en-route to agent actually means when ICM reserves an agent and sends the information to Call Manager to make the phone ring. when the phone is about to ring, if the agent un hooks the receiver or if he goes to the aux mode the call will fail. This call is listed under the abandoned calls en-route to an agent. However the number of failed count due to this is very less. If you see more number of calls in calls error, you would also need to verify other scenarios on the network too. As you have not mentioned whether the Contact center and the Data center components are in the same or different location at this point of time I cannot conclude on the answer. If they are seperated over WAN you would need to check on the network side also.
