This is why it is important to make sure your PBX can connect to the remote server wmp.wildix.com (see Appendix 7)
Make sure that Firewalls that limit the Internet access to the PBX, allow the traffic to wmp.wildix.com and vpn2.wildix.com on the 443 TCP and 1194 UDP ports.
Access the Wildix Management Portal (WMP – www.wildix.com/portal) using your credentials (which you must have received by email)
Go to the tab “PBXs”
Enter the serial number of the PBX into the field “Serial” and click “Apply”
