Block number blocks a nuisance caller for a while and unblocks the number again automatically. By default the person who blocks picks the duration each time. Call blocking under Admin settings, Phone system can force one fixed duration for every block instead, which is what most call centers want: nobody can block a number for a day by mistake.
Set a fixed block duration
- Open Admin settings, Phone system, tab Call blocking.
- Switch on Use a fixed duration.
- Set the Duration, for example 00:30 for thirty minutes.
- Click Save in the bar at the bottom of the page.
From now on every block expires after that time, and the duration field on the Block number page is ignored. Switch it off to let people choose per block again.
