I have calls from collection agencies that the caller id is masked. The are code appears to be coming from one state, but the call is originating from somewhere else. The calls are becoming very harassing and threatening. I have already set freepbx to record any inbound call to a .wav file so I can burn it to cd aas proof, but I was wondering if there is a method in asterisk to trace a call that is “masked”. Any help would be appreciated.
