We tried replicating the issue in our lab and we were able to replicate the issue in our lab with following scenario:
“This issue will happen when the campaign was paused and again resumed , and after resuming the campaign the first call was retry , that caused the issue of NULL pointer and the thread was blocked hence no further dialing and no nailup calls”
