Keeping your 3CX IP phone<\/strong> firmware current improves security and reliability. In recent updates to the 3CX system<\/a>, several changes have been made to the IP Phones to improve security and simplify the configuration process. In this blog post, we’ll take a closer look at the updates and what they mean for users.<\/p>\n\n\n\n

Quick answer:<\/strong> To update a 3CX IP phone, log in to the 3CX Management Console, open Phones<\/em>, select the device, and apply the recommended firmware version \u2014 the phone reboots and updates automatically through auto-provisioning. 3CX supports Yealink, Snom, Fanvil, and Grandstream handsets, and running the latest approved firmware is the best way to maintain security, call quality, and compatibility.<\/p>\n\n\n\n

3CX Update 6 Enhances Support for IP Phones<\/strong><\/h2>\n\n\n\n

After being marked as end-of-life by vendors, some IP phones<\/a> were unable to keep up with security updates in 3CX’s Update 5 and were removed from support. However, with the release of 3CX’s Update 6, these phones are once again supported and functional, able to be configured both locally and remotely. It’s important to note that if you don’t already own these phones, they should not be purchased as they will not receive any future firmware updates and could be subject to removal if a security vulnerability is found.<\/p>\n\n\n\n

Good news! With Update 6 Alpha, Yealink<\/a> has released new firmware for its T29G, T46G, and T48G models to ensure secure provisioning with 3CX once again. The firmware has undergone extensive negotiations and discussions to ensure maximum security and compatibility.<\/p>\n\n\n\n

And it gets even better! With the final release of Update 6, Yealink has added more models to the list, including the T41P and T42G.<\/p>\n\n\n\n

The Yealink T27P<\/a> has made a comeback, but due to the lack of updated firmware from Yealink, it can only be set up within a local area network (LAN). This means that the phone can only be configured through a direct connection to the network, rather than remotely through the internet.<\/p>\n\n\n\n

To ensure the best experience, it is highly recommended to update your phone to the latest firmware version before configuring it. This will ensure maximum security and optimal functionality.<\/p>\n\n\n\n

Snom<\/a> D120<\/a>, D305, D375<\/a>, D745<\/a>, 710, 720, and 760 SIP Phones are once again available for use! However, it is essential to ensure that these phones are updated to the latest supported firmware before configuring them through 3CX. <\/p>\n\n\n\n

Manual Provisioning Solution for Older EOL IP Handsets<\/strong><\/h2>\n\n\n\n

Despite efforts to bring as many EOL IP phones back into support, some models just cannot be securely provisioned with 3CX. To accommodate users of these older handsets, manual provisioning guides have been updated to provide a solution. This involves specifying the registrar\/SBC IP and AUTH ID through the phone’s web interface. This solution is only for existing users who already have these older IP handsets, and purchasing such outdated phones is not recommended.<\/p>\n\n\n\n
