Description:
Customer is requesting the ability to assign an existing direct (extension) number as the main company number, while still retaining full functionality of all existing number assignments.

Current Limitation:
At present, when a direct number is assigned as the main company number, its role is changed within the system and it cannot simultaneously remain assigned as a direct extension. Additionally, the original main company number cannot remain independently assigned to the Auto-Receptionist without reconfiguration.

Business Use Case:
The customer requires the following configuration flexibility:

A direct extension number should be usable as the main company number (public-facing number)
The existing main company number should remain active and assigned to the Auto-Receptionist / IVR system
The same direct number should continue to function as a personal direct extension line

This setup is needed for organizations that want to:

Rebrand or change their primary public-facing number without disrupting existing IVR flows
Maintain continuity of established Auto-Receptionist routing
Avoid reassignment or disruption of user direct extensions

Requested Enhancement:
Enable the system to:

Assign a direct number as the main company number without removing its direct extension association
Allow the original main company number to remain assigned to the Auto-Receptionist
Support multiple number roles without forcing reconfiguration or reassignment

Impact:
This enhancement would provide greater flexibility in number management, reduce configuration limitations, and better support real-world business scenarios where companies need separation between public-facing numbers and internal routing structures.
