You can control Call Barring at either Site Level, or at User Level.
There are seven call-barring options. These are:
- Allow free phone calls
- 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 that 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 as a result of 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.
