Blacklist

The Blacklist feature provides screening of calls from incoming routes. Any blacklisted number will be applied to all active inbound routes.

Extensions cannot be added to the blacklist.

 There are two ways to add/modify/delete a blacklisted number:

  1. From the UCx Web-based Configuration Utility
  2. 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:

  1. Open the UCx Web-based Configuration Utility
  2. From the PBX tab, select PBX Configuration
  3. From the left side column, select Blacklist
  4. Enter number to blacklist in the Number field
  5. Click on Block Unknown/Blocked Caller ID if you want callers with unknown or blocked Caller ID information to be blocked (i.e. blacklisted)
  6. 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
  • Unavailable
  • [blank] (no value at all)

Note that 'Anonymous' is not included in the above list, you have to manually add to the blacklist. The values are also case-sensitive, so you want to add both 'anonymous 'and 'Anonymous'.

The feature codes for Blacklist are defined in the Feature Codes page.

From a user's extension, perform the following steps:
