Blacklist
The Blacklist feature provides screening of calls from incoming routes. Any blacklisted number will be applied to all active inbound routes.
There are two ways to add/modify/delete a blacklisted number:
- From the UCX Web-based Configuration Utility
- From an extension using feature codes
A number added to the blacklist from the Web-based Configuration Utility can be modified or deleted from any extension, and vice versa.
Configuring Blacklist from UCX Web-based Configuration Utility
To add a number to Blacklist, perform the following steps:
- Open the UCX Web-based Configuration Utility
- From the PBX tab, select PBX Configuration
- From the left side column, select Blacklist
- Enter number to blacklist in the Number field
- Click on Block Unknown/Blocked Caller ID if you want callers with unknown or blocked Caller ID information to be blocked (i.e. blacklisted)
- Press the Submit Changes button
All the blacklist entries are listed on this page. You can use the Delete or Edit links to delete/modify the entries.
Block Unknown/Blocked Caller ID
If the Block Unknown/Blocked Caller ID field is checked, the following values will be included in the blacklist:
- Unknown
