RingCentral Multi-Site Support: Setting Up and Managing Site Codes

After enabling Multi-site Support, you may configure the RingCentral Multi-Site Codes. Multi-Site Codes allow you to define a dial plan for intra-site and inter-site calling. With Multi-Site site codes, Users within a site can call each other using short extension numbers, and use full extension numbers when connecting with Users between sites.

Multi-Site Codes Nomenclature

Use the following information as reference when setting up Site Codes.

• A field available for accounts with multi-site support capability turned on.  
• Used by organizations to designate specific sites within an account.
Site Code 
• Site-specific extension code designed to efficiently categorize and identify specific extensions between sites
Full Extension Number
Full Extension Number = [Site Code] + [Short Extension Number]

Example: A Site with the following Site Code and Short Extension Number will have the indicated Full Extension Number.
       11         +                    001                      =                  11001
[Site Code]     [Short Extension Number]       [Full Extension Number]
Intra-site Calls
• For users belonging to the same site, they have the option to dial using the Short Extension Number or the Full Extension number. From the example above, user may dial 001 or 11001.
Inter-site Calls
• For users belonging to different sites, they must dial the Full Extension Number. From the example above, user must dial 11001.

Disable Site Codes

IMPORTANT: When Site Codes are disabled, the Full Extension Numbers remain the same, but any configured information about the disabled Site Code and its corresponding Short Extension Numbers are lost.

In order to re-enable Site Codes, you will need to go through the entire process of creating the Site Code, Short Extension Numbers, and resolve any conflicts with the extensions to finalize the dial plan.


Delete Sites

When a Site is deleted, the existing Site assets can be re-assigned to another existing Site. The re-assignment will require having some of the extension numbers to be reconfigured, considering different Site Codes or conflicts with Short Extension Number duplication. User Extensions need to be normalized once reassigned to a particular Site. Conflicts such as duplication of Short Extension Numbers or availability of numbers can be resolved by adjusting the Full Extension Number lengths or by creating new Site Codes.

See RingCentral Multi-Site Support: Moving Assets Across Sites to learn how you can move selected Users, IVR Menus, and Call Queues to another site.
