How to Set Up: Virtual On-Net Extensions

Virtual On-Net Extensions allow you to have people that don't have phones or users to have extensions in the system. Calls can be placed and transferred to this extension, and they will route to the person's external number, such as a cell phone. When calls come in from their external number the Nextiva phone will show the internal extension and caller ID. This would, in effect, mask the external number and display the internal extension. These are extensions only and do not have any advanced call routing or voice mails (can’t set up a phone/device).

How to setup Virtual On-Net Extensions

  1. Login to the CP Portal. (link)
  2. Click on Groups
  3. Click on Search to pull up a list of all the groups on the account
  4. Select the group that will have the Extensions added to it
  5. Click on Virtual On-Net Enterprise Extensions
  6. Click Add
  7. Enter the last name and first name for the extension
  8. This will automatically populate the Calling Line ID fields, which then can be adjusted
  9. Enter the phone number that the extension will be forwarded to
  10. Enter the extension that will be assigned to the employee
  11. Select Virtual-On-Net from the Virtual On-Net Call Type drop down
  12. Click OK

How to add multiple Virtual On-Net Extensions at one time

You can click on Add Range from the Virtual On-Net Enterprise Extensions and put in a range of extensions that will be mapped to a range of external numbers. This is only useful if you have a range of contiguous external numbers to map the internal extensions to.
