Security issues Yealink firmware x.83.0.35

Posted on 21. August 2019

Dear NFON customers,

as you may have learned from the press, the German Fraunhofer Institute has found potential security issues in older firmware versions of Yealink desktop phones.

After consultation with the Yealink Development Department, we can confirm that Yealink firmwares used by NFON are NOT affected.

We strongly recommend customers who are still using old firmware version to update their devices.

  • T41P, T42G, T46G and T48G to version x.83.0.100
  • T41S, T42S, T46S and T48S to version x.84.0.53

For mass updates please contact the NFON Support.

Kind regards,
the NFON team
