In this guide, we explain everything you need to know about Call Barring in Gamma Horizon office phone system.

Call Barring

You can control Call Barring at either Site Level or User Level. There are seven Call barring options. These are: 

  • Allow calls to free phone numbers
  • Allow national calls 
  • Allow international calls 
  • All chargeable directory services calls 
  • Allow premium calls 
  • Allow mobile calls 
  • Allow 084 calls 
  • Allow 087 calls

There are two categories that need consideration: 

  • When making a call - call barring is applied to any call the user makes directly via their calling device or software, including a consultative transfer. 
  • When transferring/diverting a call - call barring that is applied to call when a user attempts to blind transfer a call to an alternative station or a divert attempt due to the call forwarding feature being invoked, a divert on busy for example. The Call barring under this heading does not apply to consultative transfers. Consultative transfers are covered under 'when making a call'. 

You can quickly view what Call bars a user has set up, both on their site and if they are overriding the site settings by using the Horizon Health Check.
