Current Behavior:

When utilizing Okta SCIM (System for Cross-domain Identity Management) to automatically provision and lifecycle new users into RingCentral, the system automatically assigns internal extension numbers chronologically/sequentially (e.g., assigning the next available number like 101, 102, 103... or 1001, 1002...). There is currently no native logic within the SCIM sync process to map a user's extension to their assigned Direct Inward Dialing (DID) phone number.

Requested Functionality:

We request an option within the RingCentral SCIM provisioning configuration (specifically for Okta integrations) to automatically extract and assign the last 3 or 4 digits of a user's assigned direct phone number as their internal extension number during initial creation.

Example: If Okta provisions a new user and assigns them the phone number +1 (555) 867-5309, the system should have a configuration rule to automatically set their RingCentral extension to either 309 (last 3 digits) or 5309 (last 4 digits), rather than just grabbing the next chronological number in line.
