Good evening… So, like PitzKey said, you need to create a trunk… Look at the image I posted… Under “Remote Host,” Type in the IP address as given by DDWW. Also, on “Match,” type in the IP address where the origination (inbound) is going to send DID traffic from.
To create the trunk: go to PBX, External, Trunks.
You also need to whitelist the IP address that DIDWW is sending traffic to the PBX from… Goto Admin, Firewall, Settings, Whitelist, and enter the IP address that needs to be white listed.
I also don’t know if you have a static IP listed with DIDWW or if you will need to enter credentials for registration. If so, on the “Trunks,” you will need to set the “Require Registration” to yes and put the information for the user name and password in the required sections.
