Feature Request: Support for Corporate Directory and LDAP on Yealink T53

Dear Product Team,

I hope this message finds you well. I am reaching out to propose a feature request to enhance the compatibility of RingCentral services with the Yealink T53 BYOD device.

Background
Currently, the Yealink T53 is not supported for the Corporate Directory feature or LDAP integration in the RingCentral Admin Portal. This limitation creates challenges for customers using the T53, as they are unable to access centralized contact management capabilities. These features are available on the supported T53W model but remain inaccessible for T53 users.

Feature Request
I kindly request the addition of support for the following features on the Yealink T53:

Corporate Directory Integration
Seamless synchronization of contacts through the RingCentral Admin Portal.
LDAP Configuration
Enabling LDAP support for T53 devices via the Admin Portal to access external directories.
Impact on Customers

This enhancement will provide a consistent experience for T53 users, aligning with other supported Yealink models.
It will reduce manual workarounds, such as manual contact uploads, and improve overall usability for organizations using the T53 as a BYOD device.

Customers who are unable to upgrade to the T53W due to budget or inventory constraints will benefit significantly from this update.
