No longer sold

Yealink stopped selling the SIP-T42G on April 1, 2020. 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.

The phone keeps making calls, but provider, TLS and codec changes can break it without warning.
