What it means

What end of life means for your SIP-T23P

No longer sold

Yealink stopped selling the SIP-T23P on June 30, 2018. 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.

Last firmware published: SIP-T23P 44.84.0.140 - Release Note (November 4, 2025)
