How do I configure cross-site dialing in Virtual Office Configuration Manager?

Note: To configure cross-site dialing in Account Manager, the legacy version of Virtual Office Configuration Manager, click here.


Cross-Site Dialing enables users to call by extension between different sites as long as they are configured under the same company (i.e., company's phone system has Cross-Site Dialing enabled). You will need to have administrator rights in Virtual Office Configuration Manager in order to set up this feature.

To configure cross-site dialing in VO Configuration Manager

  1. Log in to VO Configuration Manager.
  2. Click Sites.
  3. Click More Options (three dots) to the right of the site that you wish to edit.
  4. Select Edit from the pop-up menu.

  7. Click Save.

To make extension-to-extension calls with cross-site dialing

Though in-site dialing will remain unchanged, users will have to add the site code before the user's extension to make extension-to-extension calls between sites.

We will use the following Site Codes:

  • Acme Site A: 20
  • Acme Site B: 21
