SIP-T28P IP Phone

End of Life Announcement for SIP-T28P IP Phone

Dear Customers,

Yealink hereby informs you that SIP-T28P IP Phone has been discontinued since December 31, 2015. After the date, the order for new product would not be accepted.

Yealink does not intend to pursue new feature development on SIP-T28P IP Phone. But Yealink follows industry standard practices regarding the support of its software for discontinued (EOL) products. Consistent with such standards, Yealink will continue to offer support and after-sale service.

Yealink would like to advise that you move your product to the newer product in order to continue and enjoy Yealink’s high level service. The recommended superseding solution to the SIP-T28P IP Phone is SIP-T29G, which offers functionally richer technology.

Yealink hopes that the end of sales of SIP-T28P IP Phone will not affect the existing service relationship and service quality. We are consistently dedicated to providing you with other excellent products and services. If you have any questions regarding this discontinuation, please contact your appropriate Yealink sales representative or your local distributors.

Thanks for your continued support for Yealink!
