Call Firewall is so simple to use – literally a case of either switching from Reject All Calls to Accept All Calls to accepting calls from My Contacts Only. For more flexible use however, Call Firewall requires the use of list management – whitelists and blacklists, to be more precise. Messages via SMS can also be blocked.
These can easily be setup in the relevant screens, and it is literally a case of inputting the telephone number or (if the call is in your contacts list) name. Numbers beginning with a certain group of digits can also be blocked. Barred or blocked calls meanwhile can be added as appointment items for review at a later date, for instance in occasions when someone you know and need to speak to calls you, but you don’t know their number or have it in your contacts list.
Once configured, it is important to ensure that Call Firewall continues to run in the background – once disabled (for instance after a reboot) then your once-blocked call will of course require answering!
Thankfully, it’s possible to add Call Firewall as a startup item on your Windows Mobile device, resulting in the application running automatically with the configured settings every time you reboot your handset.
