Off hook phone shows External call after 15 sec

We have two CCM 4.1(3)clusters. In one cluster, when phone goes off-hook for 15 seconds and no digits are dialed, then proper annoncement plays and phone gets disconnected. But on another cluster, after 15 seconds of off hook status diconnection tone sounds and IP Phone displays External call. What can be the issue?

Does this happens for one phone only? Have you found any kind of event log errors or warnings on the CCM server on which the IP phone is registered?

a CUCM detailed trace can show exactly what is happening
