I'm trying to set up a SourceID rule for one of our VOIP providers, and one of the fields I am using is "From: Host Part" and Custom IP Range as the variable. My question is, how is the IP range supposed to be entered? If I enter one IP, it will accept calls but only half of the time since there are a range of IPs used for our VOIP provider. But if I enter a range such as 192.168.0.0/24 it does not work. Any help would be appreciated!
