ZelloGateway will not start if voxSampleLevel is present in the config file

[Jarynnnn]

Despite voxSampleLevel being present in the config example, if it is present in the config file ZelloGateway crashes with the following error:

Property 'voxSampleLevel' not found on type 'ZelloGateway.ConfigurationObject'.```

Not sure if this is related, but I'm also only able to get Zello > DVMConsole audio working. There's no audio to Zello and there's no audio to DVMHost
