There is one more item to look at that can cause the "Host not found" as well as a loss of ring tones on version 8.6 and later. I am not sure which version this started in but I believe it is with 8.5 that the phones started using the configuration file for the URLs to look up services. It also used the locale file to confirm the certificates. If there is "ANYTHING" that is out of place with the certificates on the servers it can cause this process to fail and the error to occur. In my case during a rehost of my servers I was forced to reload the subscriber to get the cluster working and the database to sync. In the process the servers had created some self signed certificates. My servers originally had third party certs from our internal CA server. When I finally found this thread it got me looking at the phone logs and I could see the cert validation failures. Looking at the certificates there were several for tomcat-trust issued to the server name. The self signed cert was there along with the third party cert. To fix my system it was a matter of deleting the self signed certificates for the services that I had issued third party certificates for. After a reboot all was well (at least so far). The directory now works as well as the custom ring tones have returned. ... View more

I do not have a cluster on the CCX only on CM. ... View more
