I have a strange problem with the IPCC express, it was working fine then suddenly it stopped in answering any calls and gives busy tone for any CTI-RP, regardless that all the services are working in full service including the JTAPI subsystem so I can add any new CTI ports or route points or even a resource and the CTI-RP is registered with the IPCC, but it also gives busy, In the real time console I can see the CTI call and the report is giving me that all the CTI ports was opened by the IPCC server,
I have tried many things I used the JTAPI update client from the CRS server, I deleted and added the JTAPI user, I changed the JTAPI provider server to another CCM server, I upgraded the CCM software from 4.1 to 4.2, moreover I have reinstalled the IPCC from the beginning, but the result still the same, it is a really disgusting problem for my client and I cant figure out the reason.
Is it possible that the calling search space for either the route point/route ports, or the calling number (assuming you're calling from an IP phone in the same environment) has been changed. You could get a redirect or busy signal if the CSS's don't match.
