What to know about call divert on Zen
Diverts on a schedule
The FRITZ!Box can switch a divert on and off by itself. On the Call Diversion tab, enable Switch call diversion on and off by schedule, highlight the times in the weekly overview, tick Scheduled next to the divert and click Apply. That suits a business line that should divert out of hours.
Divert only some callers
Instead of all calls, you can divert calls from one person in the phone book, a whole phone book, a specific number or range, or anonymous callers only.
