What it means

What end of life means for your SIP-T58A

No longer sold

Yealink stopped selling the SIP-T58A. New units and spares get harder to source.

Updates ending

Firmware and security fixes continue until end of life, then stop.

Limited repairs

Warranty replacement and Yealink technical support end at end of life, so a failed phone has to be replaced.
