Call forwarding and Do Not Disturb

Send calls to another number, to voicemail, or stop them ringing.

Updated 30 October 2026

You can set these in the Horizon portal, in the Webex app, or with star codes from your phone.

What you wantTurn onTurn off
Forward all calls to another number*72 then the number*73
Forward when you’re busy*90 then the number*91
Forward when you don’t answer*92 then the number*93
Forward when your phone is unreachable (e.g. power cut)*94 then the number*95
Do Not Disturb*78*79

Tip: set “forward when unreachable” to a mobile, so calls keep coming through in a power cut or internet outage.

Forwarded calls to mobiles and external numbers are charged as outgoing calls from your Horizon account.

Prefer calls to ring your mobile as if it were your desk phone? Use Remote Office or the Webex app instead.
