Repeat Outbound calls

A man called our main number on our trixbox pbx yesterday and attempted to dial an extension. Since then he has received 89 calls from the system on channel local/“his number”@from-inter. The calls last about 5 seconds, he can’t answer them fast enough. I have been on the system for about two weeks since the tech who built it quit. I know very little about freepbx, but I’m using the web gui to configure it as best I can. Any help would be appreciated. SOLVED. too simple. RESTART NOW restart gracefully wouldnt work because of the active channel he was on, so I simply restarted. I would like to know how to solve this without a restart.
