Activate blocked dialling
Your tiptel 172 provides different blocked dialling types in order to prevent unauthorised calls:
- The "complete call blocking" will block all outgoing calls.
- Blocking via "blocked numbers". All telephone numbers entered in the blocked numbers list can
no longer be dialled.
- The parameter "no call blocking" removes all call blockings (factory pre-set).
The "blocked dialling" always refers to outgoing calls. Incoming calls can always be received.
The function "direct dialling" and dialling the emergency telephone number 999 remain possible
even if the call blockings are active.
