Having installed a primary server in subscription mode, the subscriptions received should be checked.
Procedure
Connect to the primary IP Office server using IP Office Web Manager. See Starting Web Manager.
Select System Settings > Subscription.
If the system has successfully connected with the subscription server, the Available Subscriptions section will show the number of subscriptions the system has.
If the system has not received any subscriptions, check the following configuration settings:
Check that the Subscription settings match those shown in the subscription email received for the customer's system.
Select System Settings > System > DNS. Check that the values matches that used for the customer's network or a know default such as 8.8.8.8.
Select System Settings > IP Routes. For the primary server there should be a default route, that is one with the IP Address and IP Subnet Mask set to 0.0.0.0. For the route, the Destination and Gateway address should match the customer's network connection for outgoing internet connections.
The system should be set to obtain time from an internet time server. That can be checked through the web control settings (Settings > System > Date and Time > Enable Network Time Protocol Client).
