''' update the above line to suit your env

 VCS Configuration
 Create a read-only account on your VCS with API access
 NOTE: VCS must be running at least x7.2.1
 Format:
 vcs = (
     ['username', 'password', 'authentication_realm', 'base_uri', 'full uri to status.xml'],
 }

 To get the authentication_realm simply open the status.xml in your browser
 i.e. https://vcs.hostname.com/status.xml
 the authentication popup will include a string like
 "TANDBERG Video Communication Server xxxxxx" where x is the serial number
