A caller who rings the same agent every five minutes, a robocall, an angry customer who will not stop: Block Number in the left menu blocks the number in 3CX for as long as you choose, and lifts the block again by itself. Nobody needs the 3CX Management Console, and nobody has to remember to remove the block.
Before you start
- Your role needs the Block number feature. See User roles.
- An administrator can force one fixed duration for every block. See Block settings.
Block a number
- Click Block a number.
- Type the Number as the caller shows it, with country code if it has one.
- Pick the Scope: Extension blocks the caller from one extension, which you then choose. Whole phone system blocks the caller everywhere.
- Pick a Duration: 15 minutes, 1 hour, 4 hours, 24 hours, 7 days, or Custom for your own hours and minutes. If Block settings force a fixed duration, the choice is not shown.
- Optional: write a Reason. It is shown in the history.
- Click Block.
Active blocks and history
Active blocks is read live from the phone system, so it also shows blocks made in 3CX itself, marked Permanent. The countdown shows when a JEDWare block expires. Unblock lifts a block before its time.
History keeps every block made through JEDWare with who made it and why. Block again repeats a block with the same number and scope in one click, handy for the caller who comes back every week.
3CX has its own blocklist, but it needs Management Console access and a block there stays until someone removes it. Use JEDWare for the temporary blocks and 3CX for the permanent ones.
For the overview of blocking a caller in 3CX with JEDWare, see the 3CX block number feature page.
