I had some complaints today that one of my incoming SIP numbers was failing for several hours. I looked at my console and didn't see anything unusual but SIP show registry confirmed that my registrations were in a failed state. I did a SIP reload and saw this in the output: Sep 22 18:54:48 NOTICE[9997]: sched.c:296 ast_sched_del: Attempted to delete nonexistent schedule entry 312896! Sep 22 18:54:48 NOTICE[9997]: sched.c:296 ast_sched_del: Attempted to delete nonexistent schedule entry 313687! After the reload the registrations were successful. Without knowing much about it, apparently they were scheduled to retry but that failed for some reason. Any ideas? MARK.
