+Multi-Site mode attempts to avoid recording duplicate calls being broadcasted on multiple sites. Trunk recorder will not record duplicate calls on the same talkgroup for systems that have multiSite enabled. To ensure that both calls belong to the same system, Trunk Recorder will verify that both sites have the same WACN for P25, or the same multiSiteSystemName for SmartNet. By default, trunk-recorder will record the call from the first site that it receives the grant on, and any additional grants for the same call on other sites will be ignored. If you want to to specify the preferred site for a specific talk group, you can specify the preffered NAC in decimal format in the talk group CSV file.
