What's new in the 8x8 Admin Console 1.36 release?

In this release, we have introduced the following new enhancement:

Ability to block spam SMS

A majority of incoming calls aren't from your customers, instead, they're from scammers and telemarketers. More recently, these attacks have moved over to SMS, disrupting teams’ activity.

In this release, 8x8 offers phone system administrators the ability to block inbound spam SMS by blacklisting phone numbers. This blocks inbound spam SMS from the specified numbers for all user extensions on the PBX including 8x8 Work and 8x8 Contact Center users. End-users can view the list of blocked numbers on 8x8 Work for Desktop without any editing permissions. This feature addresses any security concerns related to SMS scams, such as a user tapping a link, opening an attachment, calling a number, likely to cause some issue.

Note: All admins with the ‘Company’ permission can access this capability.


  • The numbers blocked by admin apply to all user extensions on 8x8 Work and 8x8 Contact Center.
  • Users can add multiple numbers by entering them manually or copying and pasting from a CSV file or another document.
  • Numbers must be formatted in E. 164 format. e.g. +1 (408) 876 6543.
  • An error message is displayed when:
  • A number already blocked is added.
  • A number is entered in an invalid number format.
  • A number is duplicated in the modal window.

    Note: The error message is not displayed if the number is already blocked and there is no validation around duplication overall per the entire list.

Supported formats

  • Shortcodes will be supported in a future iteration.
  • Phone numbers ranges are not currently supported.
  • There are no restrictions around which phone numbers can be blocked. They are not checked against the Company Directory or Personal Contacts.

To block spam SMS:

  1. Log into 8x8 Admin Console.
  2. Go to Home > Company.
  3. Select Blocked SMS.
  4. On the top right corner, click Add new numbers.
  5. Enter the phone numbers to block SMS from. Make sure to enter it in the E.164 format (e.g. +1 (408) 876 6543)

    Note: As you finish entering a phone number, press Enter/Space to begin entering the next number.

  6. If you entered an incorrect number, you must delete the number and reenter the correct number. You are not allowed to edit.
  7. If you entered a duplicate number within this entry, you are alerted to remove the duplicates before saving.

    Note: This does not check for duplicates against the existing list.

  8. Once you complete entering the list of phone numbers, click Block.
  9. Verify the list of blocked numbers that appear.

Access the list of blocked SMS numbers as an end-user

Alert: Ability to access the list of SMS numbers blocked by admin is available on 8x8 Work for Desktop 7.26 release which will be released in Beta during mid December and generally available to all in early January 2023.

As an 8x8 Work for Desktop user, you can now access the list of SMS numbers blocked by your admin. Additionally, if you are experiencing spam SMS from unknown numbers, you can block SMS from those numbers on your end. The numbers you add are blocked from sending inbound SMS to your extension only. Other extension users in your company are not impacted.

To access the blocked inbound SMS numbers:

  1. Log in to 8x8 Work for Desktop.
  2. From the menu, click Settings > Account Settings.
  3. From the list of Account Settings, select Blocked SMS.
  4. You can view the list of numbers blocked by your admin. Note that they are not editable.
  5. To add more numbers, click Add new numbers.
  6. Enter the numbers in the E. 164 format.
  7. Once you complete the list, click Block.
  8. Verify that the list now displays the numbers you added. They appear on top of the admin list. You can delete these numbers at any time.

- Numbers blocked by users block inbound SMS only for that user extension on 8x8 Work apps.
- Numbers blocked by admins block inbound SMS for all their users/extensions, in 8x8 Work and 8x8 Contact Center.
- If both user and admin block the same phone number, only the admin record will be displayed on the users’ list, without any editing permissions.

What’s new in the 8x8 Admin Console 1.35 release?

In this release of 8x8 Admin Console, we have introduced the following enhancements:

Ability to reassign users from one site to another

An 8x8 user without a license can now have their site updated individually from one PBX to another PBX. In this release, you can move a user who is not yet assigned with a license, from one site to a site in another PBX. This gives you the convenience of redistributing users before assigning licenses.

Note: Moving users with licenses are currently only supported within the same PBX through bulk edit only.

Bug fix

We have also fixed a bug for users who want to use PBX system extensions on Line keys. You can now retrieve device line key configuration when a system extension such as call park extension is configured.
