Upgrade your Call4tel Devices to 3CX V20
Call4tel releases a firmware update letting NX32, NX32 Lite, NX96, NX256 and NX256RR devices upgrade to 3CX V20 (Release Candidate), with step-by-step upgrade instructions.
A new update for Call4tel devices is available and enables users to easily upgrade to 3CX V20. V20 is still in Release Candidate, so we advise you not to upgrade any production devices — it's for testing purposes only. However, when the final version is released, you can upgrade your production devices without worry.
This update is for the following devices: NX32, NX32 Lite, NX96, NX256, NX256RR.
Upgrade to 3CX V20 — if you have 3CX configured and installed: 1. Take a complete backup of your 3CX install and save it. 2. Upgrade your Call4tel device to V1.246 (Latest) from your Call4tel Portal > Profile > Update. Your device will reboot so ensure you do not update during office hours. 3. After the upgrade, log in to your 3CX Management Console and upgrade to 3CX V20; this takes approx. 20 minutes. 4. Once 3CX successfully upgrades to V20, the system will automatically reboot. 5. Check your Call4tel portal access and 3CX Management Console access to confirm the upgrade was successful.
From a fresh device where 3CX is not configured: 1. Upgrade your Call4tel device. 2. You can use the command "sudo call4telupgradedebian12" via SSH access, and view the live log on screen as the update runs. 3. You can also log in to your Call4tel Portal > Settings > 3CX Settings > Debian-12/3CX-V20 update; this updates the device to Debian 12 and 3CX V20 and takes approx. 20-30 minutes. 4. Once updated, the device will reboot. You can confirm the update from the settings page.
