Replacement optionsWhat it means
What end of life means for your BT40
No longer sold
Yealink stopped selling the BT40 on May 31, 2019. New units and spares get harder to source.
No more updates
No new firmware or security patches. Vulnerabilities found from now on stay unfixed.
No warranty or repairs
Warranty replacement and Yealink technical support end at end of life, so a failed phone has to be replaced.
It still works, for now
The phone keeps making calls, but provider, TLS and codec changes can break it without warning.
