OCTOBER 2019 MACWORLD 75You can get around this by
tapping the on-screen “switch to
cell” option, which reroutes the
call-in progress to the cellular
network. It’s a little clunky but
comes in handy while on
unreliable wireless connections.
Also, you can customize
what’s spoken during voicemail
greetings for whitelisted and
blocked calls, but there’s no way
to record outgoing messages in
your own voice.
Although contacts remain on
your device at all times, the idea
of forwarding incoming calls may
give some users pause. For me,
the satisfaction of purging
robocalls was ultimately worth it.
Firewall did miss a call from one
of my contacts, but infrequent
outages are routed to voicemail,
with a push notification reminder
to check recent calls.BOTTOM LINE
Firewall is Kryptonite for unwanted
calls and worth the modestly-
priced monthly subscription for a
little peace and quiet, if you don’t
mind entrusting incoming calls to a
third-party app. ■Blocked
calls from
unrecognized
numbers can
easily be added
to your Firewall
whitelist so
they won’t be
ignored in the
