To access the eFax portal, navigate to the URL https://pbx.primevox.net
Once you've logged in you will see the eFax menu on the left hand side of the screen with the following menu options: Inbox, Outbox, Trash, and eFax Settings.
Sending an eFax
To send an eFax, click the Inbox tab. In this tab you will see the big green button at the top of the screen that says "Send eFax".
You will then be able to enter the number you wish to fax or choose a number from the Phonebook, which can be edited on the Phonebook tab. You can then attach the fax document which MUST be a PDF document.
Clicking "Add Field" will allow you to attach as many PDF documents as you want - They will all be transmitted together as different pages of the same fax.
Setting up Fax-to-Email
To receive an email every time you receive a fax, go to eFax > eFax Settings. You can assign up to 3 email addresses to simultaneously receive a copy of the fax automatically.
