Once you've assigned DIDs to a fax trunk, you can send faxes from, and receive faxes to, the eFax Portal located at http://fax.sipstation.com. This portal can be used as a standalone fax-over-IP solution, or it can be used in conjunction with physical fax equipment.

Log in (and choose a location if applicable).
Click on Fax in the navigation menu.
Scroll down to the Fax Trunk to Device Assignments section. You will see available fax trunks on the left side and a list of physical devices on the right side, along with their available ports.
Drag available trunks out of the red box and drop them in one of the green boxes to assign them to a device and port.
In our example, we will assign one trunk to each of our two devices, in port 1 on each device.
The trunks appear in their assigned ports.
When finished, click the Save Fax Trunk Assignments button to save the configuration.
