Cloud Voice 84.22.0.138 V23.3

• Release date: April 15, 2026
• Release version: V23.3-GA

How to get this update

Open the PBX (Private Branch Exchange, your hosted phone system) admin portal, check for available firmware updates, and upgrade your phone system to move to this version.

Note

This page covers changes to the phone system firmware itself. Updates to the Cloud Voice App (desktop, mobile, and the browser extension) are tracked separately in the Cloud Voice App release notes.

Now that the build has moved from Beta to General Availability, it is supported for use in production environments.

Tip

If something does not behave as expected after upgrading, report it to your support contact so it can be investigated.

Changes in this release

Security

System-wide protections have been strengthened based on the findings of a recent internal security review.

Caution

Upgrade as soon as possible to receive the most complete security coverage. This build is the recommended baseline for protection.

Call

Resolved a problem with push notifications for incoming calls. A push notification is the alert your mobile device shows for an incoming call even when the app is not open in the foreground.

Previously, if a user had force-closed (fully swiped away) the Cloud Voice App on their mobile device before the PBX was upgraded to version 84.22.0.134-beta1, they stopped receiving incoming-call push notifications until they reopened the app by hand. Those notifications now arrive normally, with no need to relaunch the app.
