The picture you last put up is the ISSS settings, the deployment part is the link to the left which says "Software Deployment", once open there is a drop down on the right its usually on servers and you should see your sig server and the applications that are deployed on it (does it look good, apps deployed (usually SS/EM)), also on the drop down is CS1000 which I was mentioning earlier, when you open that you see the callserver and assigned sig server(s).
Looking at the ISSS its enabled but states "new or deleted targets found sync required" you could try the sync and activate there in case that is the issue, or you could disable it and sync/activate to test without ISSS. BTW ISSS is securing the signalling traffic between elements of the PABX, so if for example one of the devices was not holding the correct info nothing would talk to it.
Needless to say the sig server is the issue at the moment as when you stat ss in the callserver in LD 117 you should see the details of that sig server come up.
