Block Outgoing Call Types (Call Barring)
Call Barring stops a number or extension making some kinds of outgoing call: overseas, mobiles, or everything. It is useful for a lobby phone, a shared phone, or as protection against fraud.

Set it up
- Go to Voice → Line Manager and click the number or extension. From the Outgoing Calls menu, choose Call Barring.
- Tick Enable the call Barring feature for this line.
- Tick at least one of the options below. Barring does nothing until one is ticked.
- Save.
| Option | Blocks |
|---|---|
| Block Non-Local Calls | Calls outside the local area. Emergency and toll-free calls still work unless blocked below. |
| Block all Fixed Line Calls | Calls to landlines. |
| Block all Mobile Calls | Calls to mobiles. |
| Block all Toll Free Calls | Calls to 1800 and other free-call numbers. |
| Block all Emergency Calls | Calls to emergency services. Not recommended. |
| Block all Overseas Calls Except Australia | International calls, apart from Australian numbers. |
| Block all All Overseas Calls | Every international call. |
| Block ALL Outgoing Calls | Every outgoing call. Emergency calls still work unless blocked above. |
Good to know: For wider protection, see Toll Fraud Protection. To ask for a PIN before certain calls instead of blocking them, use PIN Code & Call Assignment on the same Outgoing Calls menu.
