When a new call arrives at an agent desktop, Agent One receives the enterprise data screen pop and one ring. Before the agent can answer the call, the call is transferred to Agent Two with the enterprise data screen pop and one ring. Before the second agent can answer, the call is transferred back to Agent One. The call switches back and forth between the two agents and neither agent can answer the call. It appears the call is in a recursive loop, as shown in . (See Figure 1.)

The problem is caused by the timeout setting between the Forward NoAnswer Timer in CallManager and the Select Resource step of the CRS script. In order tTo fix this problem, the Forward NoAnswer Timer must exceed the Timeout value of the Select Resource step.
