📌 Feature Request: Ability to Send Fax Using Extension Number Instead of Full Phone Number

Summary:
Request to enhance faxing functionality in RingCentral to allow users to send faxes by entering an extension number instead of the full 10-digit direct number.

Details / Business Need:

Currently, users must enter the full direct phone number assigned to an extension to send a fax.

Users want the ability to enter only the extension number, similar to how internal voice calls work.

This enhancement would simplify the process for internal fax communication within the organization.

Problem Statement:
The lack of support for faxing via extension numbers creates inefficiencies and confusion for users accustomed to using extensions for internal communication.

Proposed Solution:

Allow users to send faxes by entering a 3–6 digit extension number.

The system should map the extension to the corresponding direct number automatically.

Maintain full logging and delivery confirmation as with standard fax transmissions.

Use Case:

Internal teams frequently exchange documents via fax.

Using only extensions will reduce the need to look up or memorize full numbers, streamlining workflows.

Impact:

Faster fax operations.

Improved user experience.

Reduced errors from incorrect manual number entry.

Workaround:
Users must continue using the full 10-digit number for faxing until the feature is implemented or search Contacts first and send fax.
